My WH has been pretty mean to me for about 3 years before he left. Back then he had, I think, a PA. (He said it almost happened once before this, so this would be affair #2). Then he got nice (I guess it ended). Then towards the bomb he got mean again, and coincidentally I now find out that he had decided to "take a mistress" when he left. A few months after he left, she went with some other guy. This would be attempted affair #3 over 5 or so years.
I'm thinking that he's maybe really not husband material anymore. I mean, the happenstance around a WH finding himself in a PA once is one thing. But the above?
