Hi ForLP
Have you gone to therapy? if you were attracted to an active alcoholic, there is something very unhealthy going on with you. (I say this due to my own experience)
If you don't want to have this same person in a different body in your next relationship, you need to take a good look at you and what you think you deserve in life. (Many of these things are unconscious).
I left years ago and now I understand partners are meant to ease your life.
Let him go and go No contact.
No one deserves violence.
At this point I do not believe its healthy to stay friends with an ex. At least not an active alcoholic ex. And not immediately after a break up. It brings confusion.
