I'm a LBH who's W was/is having an EA. This has been ongoing for at least 15/16 months that I can tell, maybe longer. I think it might be dying down now and W is having second thoughts. We've been separated going on 14 months and emotionally/physically detached for 17/18 months. I now have OW and am starting to get the feeling my W is trying to reconnect with me. She's really poured it on since she knows I've become somewhat involved with only one OW. Not so bad when I was dating multiple OW, but this one in particular is affecting her.
I don't know if I have the same feelings for her anymore and sometimes I wish she would get the notion of reconciliation out of her head so I won't have to deal with it. I don't mean to discourage you, I'm just being honest as a H who's W deceived him and was not faithful. Maybe I can help you see his point of view.
There's a very huge trust factor involved. I'm not sure I can trust W anymore and that steels from my attraction for her. Her past actions and treatment of me have affected my physical attraction to her and that's a biggie to overcome. OW looks better at this point. This is what your WAH might be going through now and I would suggest doing anything possible that rebuilds that trust. Your still early enough in this process to retrieve your H's attraction so you need to stick with it if you want him back.
