Welcome to SR.... we are glad you found us..
Holy Cow that is some ride you have been on. I personally know how hard it is to end the relationship... well I did not end them, he did but its hard to let the relationship go.
This disease is progressive ... it just gets worse and worse. When you said abuse??? That is a different issue from his drinking, Please keep yourself safe hon. Is there somewhere you can stay till he finds a place? I might suggest that there is a timeframe that he has to be out... they can make it dragg on forever sometimes.
Keep posting, I look forward to getting to know you!
