Heartbroken, I think Old Timer is right. You need to LRT. Do you have a good lawyer? Can your husband afford to fully buy you out of the house? If he can't I wouldn't just give it to him. I thought about arranging things so my husband could stay in the house with the kids, but as one of my friend's pointed out. It's a chick magnet. So I figured... naw.
Is the house large enough that you could rent out a room or two? Maybe to some cute guy! I thought about doing this.
In my sitch, my husband's family (except for his mom) told him he had tried his best and it was time to move on. His sister even set him up on dates!
Obviously not agreeing with your husband on this point isn't helping (the cheeseless tunnel), maybe it's time you agree with him. He tried so hard, isn't happy and you want his happiness. This is not giving up. You can always agree, go with the flow, but still be cordial and friendly and still "leave the door open."
Read LRT over and over and over... just do it. Find your own place without your husband's help. If he happens to call say you have some friends helping you find a place so he doesn't need to bother.
Grrrrrr....
There is no arriving, ever. It is all a continual becoming.
