How long would you try to do this? It is extremely hard, and what will YOU be gaining? There must be another way....but it is very difficult financially to physically separate.
Mine had to stay for a month to find place. This house has room for us to be separated but he would come in falling down drunk, bumping off walls, etc and it was awful. Silence was golden, but annoying to have someone under the roof like he was. Hated seeing him pack up and leave, tho. BUT, there was an immediate sense of peace, with it.
