I understand this very well and big ((hugs)) to you but I want to point out something:
Notice how everyone has their story and while a few are different, most contain a bit of this same thing...an older, less attractive AP who thought it was awesome to have an affair with a committed man...a young, fabulous thing who thought it was awesome to have an affair with a committed man. You either know or can bet that most of these women were feeling pretty high because they could take what was someone else's. notice too, that these AP's are vastly different from each other in looks but they ALL did pretty much the same thing, with the same heart and spirit.
Gorgeous, young and hot.
Older, rounded grandma.
Older, fatter, uglier, younger, beautiful, plain...THEY ARE ALL THE SAME.
Believe me, as any other BS can tell you, it hits the self esteem NO MATTER what the AP looks like or has supposedly going for them.
And in the end, none of it is you.
None of it at all.
Perspective...I was fantastically gorgeous. I was a bigger built girl, not fat but not tall and willowy. I had my own fan club. I mean, actually...not figuratively. I did some modeling as an artists model. I was the icon for one of the sites that causes many spouses troubles. I was no 100 lbs but it made no difference.
You know what? I got cheated on.
I got very sick, gained a lot of weight....even so much fatter, I still attracted tons of attention although there was no way I'd get in a bathing suit. I got cheated on.
I lost most of the weight, worked out a lot, changed many things in myself for the better. Older, much wiser (that took real effort!) and...I STILL got cheated on.
I am struggling with wondering why, no matter what I do, I'm never good enough...but in truth, I'm pretty amazing...it isn't me. I've got my issues but I'm also pretty self aware and always working on being more so. It isn't me.
It isn't you.
I think of my ex MIL. She is a smug, self righteous woman. Ugly as home made sin. Unapologetically bearded, teeth missing, feet that can out stink a skunk any day. She's no beauty...inside or out. Very hurtful. Her husband never cheated on her and has always treated her like a queen that he has undying passion for. He's cuddly, cute and playful with her. He hugs her and pinches her butt. He never cheated on her.
Was it her? Nope.
It's him....
It's not us. It's not you and it sure as fuck isn't the AP. They are just willing and there. They are different. No one can compete with different because everyone is different.
It's him.
I'm willing to bet, you are quite lovely. I'm willing to bet your combination of brains, motivation, heart and freckles is more than enough to cause any number of men to feel giddy.
If you wanted to be a home wrecker, you could be but you clearly don't want that...and that IS you.
WS will often not know what to say when their AP says something negative about the BS because they are shook out of fantasy world and when they are shook, they know it isn't true and they suddenly know that THEY aren't true. They often don't want to say something to piss off the AP because they don't want to dwell on the reality of their BS or family etc...they don't want the intrusion of reality in the fantasy bubble...so they say nothing so it will go away.
You sound amazing. Go be amazing and recognize his failings as his...not yours.
As for the O thing...she may have faked it, she may not have. There are a billion things that can make it happen or not. He may have taken that as an ego boost and you have taken it as a hit but I'd suggest that it indicates nothing. O can happen at the oddest moments or not at all even though deep love and desire were present. If he really wanted to feel an ego stroke, he should have been investing in you and your O.
Sorry for the ramble. I feel you but really, you sound fabulous.
