Welcome to SR but sorry you had the need to find us.
When I was making the decision to stay or go (I ended up leaving) I found a wonderful counselor that specialized in working with families of addicts. I also started looking at employment options for myself and setting aside any money I could. I had a friend who I could stay with temporarily when things got out of control.
I also went to a free consultation with an attorney.
Please don't hesitate to seek help from DV services. My AH went from only being verbally abusive to physical very, very quickly.
One of the mistakes I made was telling him too much about what I was doing. I told him I was going to Al Anon. This made him extremely angry and was part of his justification for his 1st instance of physical abuse.
