And re my home, no, my wife and I weren't having sex.. OM's been gone for over six months, we still don't have sex... we have gone out together maybe six times only at her initiation.
But my wife wasn't gloatin about her bachelor pad on the phone to me a couple months ago nor was she gloating about going out on dates either, she was pretty ashamed of the whole affair and for the most part didn't flaunt it in my face like your H has done.
He's got to learn to build trust, and as you pointed out, he's not doin a smack up job right now... so I say test his commitment... If he can't DB for six months while you are NOT cheating, and NOT divorcing him... Good lord... If he can't take that he's not gonna last long term...
There are people here fighting for their marriage under terribly painful circumstances, your H would be fighting for his under OPTIMUM conditions... If he STILL gives up under optimum conditions well... He's just not grown up yet and needs more time on his own working with professionals.
