Hoju, I'd watch what you say to Dawgy in that regard. He's a babe magnet from what I can gather and going to a bar and trying to pick up a girl is not the right tact for him. He's already had a couple women try to woo him. Luckily he's been strong enough to resist them - still heroically committed to his marriage. I don't think his confidence issue is anything more than being worn down from the constant rejection of his live-in WAW.
Dawgy, consider this: offer for her to move out. Try to make a plan with her in that regard. You can even help her find a place. Just tell her it's better if you're apart for now. That way you'll be away from the daily in-your-face rejection and she'll be free to consider the consequences of her choices. I doubt she would ever expect you to offer that - but it's definitely a 180 that may make her think.
Just an idea.
