I posted earlier about this - I actually have a very close friend that left his wife for another woman for about 1 year, 9 mo - even got a full-sleeve tattoo designed by the other woman. His wife stayed, and he eventually got tired of her, and came back.
Another couple I know - same deal, guy left for approximately 2 years, but came back; they're so in love they're almost too mushy, and it's 5 years later.
I don't know of any women who left that ever came back, but I don't know as many situations, either. I think women tend to become more emotionally hurt and walled off. My ex-wife was also a WAW (6.5 years ago), and although I wouldn't consider re-uniting with her, she respects me, defends me, thinks I'm the best dad in the world, even says now that the things she took so wrong back then were probably skewed in her mind.
