chero, if he is sober and does some temp sweet talk, won't you melt and probably stay. Then have to go through this again.
Please find a neutral place. My soft caring loving heart would give in right quick if alone with him.
If it is true love, it will be there when and if he gets sober and wants to be sober.
You can hire movers and take a friend, meet the movers there, then put it in storage till you know what to do.
Just don't go to the house and be alone with him.
