I just have this feeling that you and your son will find a place for the two of you (or stay in your current home, and your AH will move out), and the first night the two of you are alone for real, with no specter of your AH coming back from an out of town trip, or coming home drunk...that the two of you will just EXHALE, and it will be the start of a totally new life for both of you.
((HUGS)) Love you, friend!
