Hi Constant learner,
I identify with you on some levels, if you read my story, my affair was born in coping with some of the same marital issues. And, like your husband, mine had a period when it seemed like he was rugsweeping or a little too accepting in the beginning. I think it's important to understand that in a state of shock the initial reaction doesn't become the permanent reaction.
For months following the affair I was pretty sure it wasn't fixable for me. I was still swept up in what the affair felt like and to compare that in an emotionally flat marriage it seemed like I just couldn't begin to want it. And for my husband he was kind of the energy of "We can separate but I don't think it's going to make either of us happy, but I won't hold you in our marriage if you are unhappy". I really resented that in some ways at the time. Now, I see that was exactly right logic to a very illogical situation.
But, as I emerged from what some call the fog, I came face to face with what I was about to lose. And, about that time his emotions had kicked in and the tables were about to turn.
The only advice I can give that helped me was that I told myself no decisions for 6 months. I prayed and was still. I read, went to IC, prayed, and worked on myself. I can tell you before much time had passed at all I saw the truth: I wanted my husband and my marriage very much. The affair was an avoidance mechanism into an alternate reality, and when initially returning to it I didn't want to let the fantasy of "deserving something better" go.
I think in some ways you've lost the validation you were getting in the affair and you are looking back to your husband to validate you by having these sweeping "fight for me" emotions. You think you have already done the work, and that you know your whys. I could tell you some surface whys during the affair and maybe a few more after the affair, but I can also tell you that the digging continued and I have learned way more than I thought I was going to. Some ugly truths about myself and motivations behind my actions and I have started being vigilent about those things and more things will come. This is how healthier boundaries are born.
Having an affair doesn't make me a unsurmountable piece of trash, it makes me human. I don't feel like I am a worthless POS, that isn't my reaction. I chose to do something that was against my moral code, against my religious beliefs, and I hurt my husband very deeply. It took some time before he could grasp that as well because like your husband, the emotional connection within himself is often eclipsed by his logic. Now, we are both very intentional, and consider ourselves in early stages of reconciliation. And, guess what? He may not choose to stay married to me at some juncture if he finds this to be a deal breaker and that is his right. For me, I know I will stay no matter what.
So, I am just trying to say, I could have written parts of your posts in those early post DDAY months. And, I too thought there was some sort of post affair script or mantra that I could not align my beliefs with.
Now, I see why they are the post affair scripts, they are true just like clichés or what have you. You do have to fix yourself. And, if not for your existing marriage, for your potential future relationships. Cause, guess what? They will be lacking in some other way, and you may talk about those issues with that person and they may not connect with what you are saying. I think of it as there are three pillars to a good relationship: emotional connection, physical connection, intellectual connection. And, in any relationship one of those pillars is often weaker than the rest. Every relationship has those recurring issues that become hot buttons or gridlocked (as to quote Dr. Gottman). Your coping mechanism can't be to have an affair.
I say all of this to someone who has been in your shoes, and without judgement. Unless you give this some time and energy you are short changing yourself to have what you want. So, don't be so quick to dismiss all of this as post-affair script. This site is composed of Waywards, Betrayed Spouses, folks that chose reconciliation, those who chose divorce, those who are divorced but wouldn't have chosen it, those who are still on the fence, and everything in between.
