You're not stupid PerfectStorm! You're just grasping at straws trying to fix something you didn't break, and you thought showing him this site would help.
It could help him, if he chooses to dive in and do the work. If he chooses to stay after the very tough critics here see through the bullshit he tries to feed them and refuse to let him get away with it. If he chooses to be honest, even if that means that he's going to have more than a few 2x4s thrown his way. Right now those are big IFs though.
You can't go back and change it now. Honestly, I do hope he gets help here! Just follow HellFire's advice and make sure you are paying attention to his words and actions, because now that he has this site, he has the remorse "playbook." It's not that you don't want him to learn how to be truly remorseful, it's just that unfortunately, someone who isn't remorseful - who is just manipulative and doesn't want their life turned upside down - could come here and learn how to mimic remorse. Be aware that just because they are saying the right things doesn't always mean they are doing the right things. Look for the actions, not the words.
And if there is anything you do not want him to know, do NOT post it here. He's a proven liar, so his promises not to read what you post are as moot as his wedding vows.
So on to your actual story. They've been messaging in some form or another since 2008, so 12 years. You've been married for 15 years. That means that for 80% of your marriage, your husband AND your best friend were actively lying to you. You don't say much about this in your initial post, but how was your best friend around your husband when the two of you were first dating? Did you ever feel like she was showing interest in him? Did she marry her husband before or after you married yours? I ask because I wonder if she fancies herself in some sort of perverted competition with you, one that she decided to keep to herself. Did you ever get the sense that she was jealous of what you and your husband have? Did she ever say anything about whether your husband was a better "catch" than hers? You don't have to answer any of those questions if you don't want to, I guess I'm just thinking that answering them, even if only to yourself, might help you get a little clarity on why she would do this. Other than just the classic, "because I wanted to," which is true of all cheaters.
Always home with us. No unaccounted time away. Their PA was so quick. She literally would meet him right off the high way on his way to work. A quickie and then off to work he went.
Many of us have spouses who we thought weren't cheating because there was "no way." It's not your fault that your brain didn't do the mental gymnastics required to put all of this together, especially if he wasn't treating you any differently. As the truth continues to come out, you might start putting some puzzle pieces together about how some of his behavior might have been off, but trust me, they aren't things that any normal person would have noticed, because our brains don't function in the deceitful, manipulative ways that theirs do. You can't see what you aren't looking for. My XH ended up having an exit A and left me for the OW, and I was super suspicious of all of his weird ass behavior during that time, which ultimately lead to me catching them. BUT I found out after DDay that he had been seeing escorts throughout our ENTIRE relationship. Anytime I had ever had any suspicions of cheating before, it was quickly met with thoughts of "But how is that even possible? Literally every second of his day is accounted for. I see him go to work, then he comes home to our daughters (my step kids), then I come home and I'm with him all night." I say that just so you know you are not alone. I felt like a complete fool for a while, until others here at SI set me straight. Many of us thought it would never happen just because time would be a barrier, but we've all found out that they'll make time when they want to.
I'm going to parse this paragraph out for you.
During our couples therapy, the therapist did have him admit that he felt entitled to it all.
Entitled is a great word for wayward behavior. Glad your therapist is on board with labeling it as such.
Not sure of it was totally due to me not giving him the time or day at that moment but my ex friend definitely caught us at our weakest and low time of our relationship.
It was NEVER because you "didn't give him the time of day." It was because he did not understand how he should act when he chose to interpret your depression as feeling slighted/unloved when he wasn't the center of attention, so he chose to do the quickest, easiest thing to make himself feel better, consequences be damned. Do you see how self-centered that all was? It was also never really about her playing this game to "convince" him because she knew you guys were at your weakest. Don't get me wrong, she did take advantage of that, but so did your husband. H wasn't "played" or "tricked." He is complicit in the same level of deceit and manipulation as she is.
The same exact thing about using excuses to get her "needs" met goes for your best friend, just change the pronouns. She was feeling bad, so she did whatever she needed to do to feel good, no matter who it hurt. Add in the huge betrayal that you were confiding in her through it all, so:
She knew exactly what I was going through. It was after our 2nd child that I was having Postpartum depression extremely bad. I was in a very dark place.
This level of deceit on her part is cold and calculating. Especially given that you've been friends since childhood, so she also knew this:
I always struggled with depression. Even as a child, all the way through my teen years and into adulthood.
They both knew about your lifelong struggle with depression, and they did this anyway! Remind yourself of that when you're asking yourself whether you can trust either of them.
I was on a bunch of random medications, experimenting what would work and what wasn't. Also I was trying to navigate life with a new baby and a 4 year old. My father had a stroke while I was pregnant and had been released from rehab right before I had my daughter and I had to take care of him as well. He was parazilzed on his left side from the storke.
That is so much for somebody to go through all at once! This is the time when spouses need to step up for each other, not run away because their needs have understandably been put on the back burner while other, more pressing things are being addressed.
So I honesly could have cared less about his sexual needs. I do take blame in that.
First, let me say that I really, really detest when someone labels their sexual wants and desires as "needs," especially in the context of infidelity. I know that sexuality is a part of being human, but in terms of the heirarchy of needs safety, shelter, food, water are all higher up. And your spouse is not a sexual vending machine for sex on demand when you just "have" to meet that "need." I'm sure a few people will be along to refute that, I'm not trying to deny the pain of those coming from a dead bedroom or whatever else, just simply commenting on how his use of "need" here comes off.
If he truly defines it as a "need" to the point where he needed it so bad that he "had" to pull over on the side of a highway for a quickie or a blowjob, well then yes, I definitely do think that the sexual addiction component is at play here, because that is incredibly compulsive. Could he not have masturbated? Not that it would take care of the compulsivity issue (trust me, compulsive masturbation is just as hurtful, ask me how I know), but at least it would not have involved this double betrayal. Why did he choose to use your friend as a living sex doll? He had lots of other choices, he chose that one. Could he not have just hunkered down with you and tried to figure out this new world order together, and let sex be on the back burner for a bit while the two of you worked to sort things out?
Which leads me to my second point, but of no less importance than the first - you do not need to take ANY blame at all for not meeting his sexual "needs" during a time when you and your family were in crisis. Pregnant with a 4 year old, the stroke of your father, then post partem with a newborn and a 4 year old and having to play caretaker to an ailing parent? Who in the world would have time for sex, let alone the drive for it? If anything, he should be taking the blame for not finding healthier outlets for his sexuality when you were clearly not in a position to participate with him. You're smart, listen to yourself:
doesn't give him a reason to go screw my friend during a time I needed him the most.
Where was he during your PPD? Was he stepping up in any way to help with the kids? Or your father? Or was he just letting you flail about trying to meet everyone's needs but your own, then using your understandable distraction as an excuse to go get some on the side? You mentioned 3x a day earlier... He had an infant, a 4 year old, and an ailing father in law, as well as this job he was supposedly driving to every day in order to have the illicit-off-the-road-BJs, oh yes, and his severely depressed wife - I have a hard time understanding how he even had time for 3x a day without some serious neglect of you and the kids.
I would bet that stepping up with the kids and your father, or even just emotionally supporting you through such a difficult time, would have gone a long way towards you feeling sexually energized again. We do not feel sexual when we do not feel safe, emotionally or otherwise.
He has always had issues with expressing himself so if I'm not paying attention (which I sure as hell wasn't at that time) then I don't know if something is wrong with him.
Repeat after me: It is NOT my job to interpret someone else's feelings, it is their job to communicate them!
He is literally doing EVERYTHING possible to try to keep us together but my feelings are just not there like they should be. I see him doing everything possible but I just feel that it is not enough. I feel like I want more but I can't even pinpoint what more I even want.
Gently, I ask, what does "everything" look like to you? Is he doing the bare minimum to contribute to his half of the marriage, as he always should have been, but because he was neglecting those duties for so long, now it seems like he's doing a lot? That can be confusing for a lot of BSs... we're so used to being the one who does everything, that even when the WS does one or two things more than what they usually do, we feel like they are going above and beyond, when in actuality they still haven't even risen to 50%. Which could be why you still don't feel like it's "enough." It might have been enough if he had done it all back before all of this happened. But now you need more. It takes a lot more effort to fix something that has been broken than it does to maintain something that was never broken in the first place.
I just don'tfeel fulfilled anymore with him. But also still can't see myself with anyone else. It's so hard to explain. I'm just lost and broken.
Just wanted to say you've been heard, and you are in good company! Every single BS has been exactly where you are. This feeling is universal. You are not alone!
