I don't believe that your H truly wants a divorce. I believe, like Saffie, that he wants a restored marriage and this is a cry for help. He wants to love you. He wants to be with you. His actions of not leaving when he could very easily go live with his Dad speak to this. But I think he is in a no-win situation. If he stays and works through this stuff, he's got tons of work to do. If he goes, he loses his wife (who he wants to love and does love) and his kids. What choice is he to make? He created this mess, he knows that. He is wallowing in this mess because he can't find the path out of it. He can't listen to you direct him because you're angry and rightfully so and he probably doubts what you say (not because you've given him cause to, but because he f'd up majorly). He has no choice but to own this problem and fix it himself. I don't know if leaving for a weekend would provide him with some time or not to reflect and gather himself together, but it might. And it might provide you the same...
I tend to agree with this. A truism of life, but most CERTAINLY true for those in (or recently over) affairs:
Judge them by their ACTIONS, not their WORDS.
Now, you may decide you don't want him ANYWAY, but base that on factors other than what he's SAYING, would be my advice.
