Your WAW will come up with all kinds of reasons why she's not happy. I've heard those 4 things from mine before, almost verbatim. My W:
Criticized that I read books more than she does
Criticized that I play golf. Not that I play golf too much, but that I play at all. The last round I played was in 2012.
Castigated me for saying something 15 years ago about us "not deserving a vacation". I remember saying that during a time of financial stress. Never mind that we have taken at least a dozen vacations since then with my full enthusiastic support.
She's attacked my worth as a husband and as a man.
She's the one who decided to cultivate an EA with OM, but she blames me for putting her in a place where she was vulnerable. SMH
My point is that a WAS will dig up anything they can to justify why they feel the way they feel. That's where the rule about not believing anything they say comes into mind. If they have a complaint that you feel is valid, then honestly address it and work on it for you, not for her. But don't get sucked in when she's spewing nonsense. They may not know it, but they want you to remain strong, even when they're floundering.
And I hate to say it, but Mozza is right. You need to make sure there's not an OM, even if it's just in her own mind. Women aren't often willing to blow up their own family unless they think there's someone better waiting in the wings. My W says she hasn't been happy with me for a decade, but it's interesting that she didn't get unhappy enough to want to leave until after she decided that OM got her motor running back in August.
