Pogre,
It's easy to get caught up in the "should haves," and I feel your pain there. (Mine looks like, "I should have considered what might be affecting his libido and not taken personally...I should have asked him about it. I should have been more persistent.I should have known he knew about the A and that was causing him to withdarw further.").. As always, it's not your fault, and I'm sorry you're hurting. It will probably just take you some time to accept the "didn'ts," if that makes any sense, but I think it helps to focus on what you know now and what will be different going forward.
Experience can be such a cruel teacher.
Here's where I go off SI script when it comes to my situation. I get caught up in guilt cycles. Like, I know it was her fault for making the decisions she did. I know that, but I also know she desired me. I not only had some of the physical side effects from the SSRI, I also had some (also well documented) psychological and emotional side effects in the form of emotional numbing.
I stopped caring about a lot of things. I'm an audiophile who loves music. I stopped even enjoying that. I stopped getting goosebumps from certain pieces of music that used to stir a lot of emotion in me. The compliments and the sweeter side of me dried up. I wasn't emotionally available to her. I started not taking care of myself. I lost an alarming amount of weight. There were a couple of occasions when she walked out into the living room topless while we were having a conversation, but she might as well have been dressed like bozo the clown for all it did for me.
Then, while I was losing weight she started gaining a lot of it. Around 50 lbs, and she's 5' 4" tall. And honestly, that didn't do much with my already nonexistent libido. She felt fat, ugly, and undesirable. She thought I wasn't attracted to her anymore, and in a way she was right. But I wasn't attracted to anyone or anything. It wasn't just her. I had just lost all desire across the board. I had stopped paying attention to her.
About 3 years ago she was promoted at work. She went from pretty sedentary type of work to more physical work that involved a lot of walking (she loves her new position, btw. Win-win). Some of that weight started coming off, and when she noticed it she actually started putting work into it. Changed her diet and started eating healthier. Over the last couple of years a lot of that weight she'd gained started melting off. She continued wearing the same (now baggy) clothes and I didn't really notice it. AP sure did tho... that's when the over the top compliments and unrealistic levels of compassion and understanding started flowing. He played her like a fiddle, and she was starved and primed for the attention.
She didn't go looking for an affair. She even resisted it a little bit at first, initially rejecting his advances, but he was persistent. She eventually gave in to her desires and instead of coming to me she ended up getting a hotel room with him under the guise of sleeping over with a friend who's husband was in the hospital. "She was scared and in need of some company." Most of that was true, but really was just a good cover story to explain her being gone for the whole night. She did that 2 more times before I caught on, did a little detective work and found out where she was.
Like I said, I know intellectually that her decisions are her responsibility. Her "fault" so to say, but I'm also very convinced she would never have done it if I hadn't checked out like I did. I'm all but certain that's the case. She's over the moon that I'm "back." She was very hurt and disappointed, angry even, that I had lost desire for her. She thought it was because of the weight gain. She was deeply ashamed and embarrassed about it. I know that if I hadn't checked out and lost interest in sex of any kind it never would have happened. She's still very much physically attracted to me, as I am to her again now.
All she wanted was her husband and I deprived her of that. Hence, my feelings of guilt. Our relationship was in the toilet, and it was definitely at least partly my fault. SSRI side effects and all. I could have been more self aware. I could have noticed it more. I just kind of let it happen. I didn't get curious and dig into why I had lost interest and had no libido. I just didn't care anymore.
I eventually did do that. I learned about the drug I was on and realized that those side effects lined up with what was happening in my life, but the damage had been done, and stopping taking it wasn't like flipping a switch. Those side effects can take years to go away, and in some cases can be permanent!
I started coming around more and woke back up so to speak, but by then he had his hooks in her. She was a couple of months into the emotional part of the affair and 2 weeks into the physical part of it. To say I was devastated would be an understatement. I know everyone says this, but I was certain she just wasn't the type to have an affair. She was a virgin when we met and had almost 27 years of demonstrated fidelity by that point. It was shocking.
The timing of certain events - me checking out of the relationship - her weight gain and subsequent weight loss - her epileptic seizures increasing in frequency and losing her driving privileges and independence (which was emotionally and psychologically devastating for her) - AP who is also epileptic and still drove stepping into the picture with unrealistic amounts of understanding and compassion for her situation - all converged into one great big perfect storm.
That all was well over a year ago now. I'm back and better than ever. I've gained a lot of weight back. She's lost a lot of weight. For the first time in years I weigh more than she does. We're both very healthy. I look good and she looks amazing. We went out and got her a whole new wardrobe. Things are... good? Well, except for the fact that infidelity has marred our relationship. I struggle with that, combined with the knowledge that it likely would never have happened were it not for the chain of events I described above.
We have a somewhat unique situation with a lot of the same tropes, actions, and words that are typically found with most affairs. I think that's why I've been as forgiving as I have (without having actually quite forgiven yet), and why we're doing as well as we are this early in the game. It's a real mess, but I don't really feel like I was truly replaced or that she stopped loving me. I'm carrying a lot of guilt and at least partially blaming myself, even while she doesn't blame me at all. She's owning it, but I'm a bit of a mess still. I will say I'm glad I have my wife back, and I know she's thrilled to have her husband back. I just wish, more than anything, we'd have gotten here without the treachery and hurt of betrayal.
I'm sorry for rambling, but you did give permission to wander off a bit, and some of the subject and replies from the other thread got me thinking about it. She admitted that sex was a big factor in why she did what she did. Just as much if not more than the validation, and there are some substantive reasons for it.
