Did You ever ask Your WW why she stays with someone she feels nothing for, is she willing to live like that for the rest of her life?
I know there are many patronizing excuses WWs give or they try to just say nothing. But it's hard to avoid the feeling that the affair and the deep attachment continues.
My wife doesn't feel "nothing" for me. She loves me; I know that. She tells me all the time and is very clear about it. People reading this may think I'm deluded on this point; so be it. I think she has issues around sex, which I can only guess at, but here are my theories.
She's very attractive, even though she's approaching 60, and still turns heads. A few nights, the husband of a cousin, a guy of about 40, was saying repeatedly how much he was attracted to her*, that his friend felt the same, and what did my friends say when I got together with her? He never quite uttered the words, "You're punching above your weight," but that was part of it, for sure. Now - so what? Well - bluntly - an attractive woman can have sex whenever she wants. I think my wife had regular one-night stands when she was in her 20s/30s. No problem. And I believe she was quite relaxed and direct with that, i.e. if she fancied a bloke, she's just say, "Right, you're coming to bed with me," and I bet she was rarely turned down. However - this also probably meant that for every man she was attracted to, there were ten or twenty others who were trying to get her into bed who weren't interested, and this was probably going on constantly. That kind of constant attention - though some people would probably say they'd love it - could be very wearing if it went on for years, which it probably did. Also, there's a fair chance that, at some point, she has been raped or sexually abused. I know she once said (not to me, but I overheard it) that she has been in at least one situation in which she "couldn't say no" (i.e. the man was going to have sex with her whether she consented or not.) So, I wonder - did she choose me because, consciously or subconsciously, she knew she could say no to me, and be done with all the bothersome sex? Clearly, this doesn't account for the affair(s), but it could be a factor.
She has given me some clues lately that she has been, in her adult life, treated as a sex object. Clues only, probably given subconsciously, not to be over-interpreted, but that's a possibility and a reason why she might want to avoid sex in our intimate relationship.
Some women - and one contributor here (can't remember who) has expressed this with admirable clarity - find their sexual attraction for their partner plummets once in a committed relationship.
Or, alternatively, she might have married me based on our definite intellectual attraction and realised, too late, that she'd married someone she wasn't sexually attracted to. Or - none of the above. What does Occam's Razor say?
Furthermore: her mother had an affair when my wife was (I think) in her teens, and her dad, great guy though he is, is not a particularly strong character, at least socially; I think my wife struggles because she can't feel as proud of him as she'd like, and I think women have a strong desire to look up to their fathers. Psychology tells us that we're attracted to what we find familiar - did she see something of her father in me? A man who would tolerate infidelity and just shut up about it? (Clearly, so far, she's right about that.)
About a year after we married, my wife made a very serious attempt on her life. It wasn't a cry for help - she meant it to work. I don't, to this day, really know why. I know she'd be devastated if we were to separate.
I'm very happy for people to engage with what I've said here, and offer perspectives I might not have noticed but, even if what I've said above seems inconsistent and contradictory, please remember that people can be highly inconsistent and irrational, as is the case in some affairs.
(*About 48 hours after this event, it occurred to me that I should not have allowed this man to talk about my wife in that way and, if it happens again, I will stop him. He said this in front of his wife (my wife's relation) also - but that's their business.)
