Hi Daniela,
I was married to an alcoholic who eventually died. I had to escape with my son to save myself and my child. It sounds like you don’t have children, which is good.
My advice to you is…..it will never change. You sound young. Please don’t waste any more of your time on him and cut all ties. Only he can help himself, nothing that you do will make any difference. You have to think of yourself, save yourself and leave.
Don’t let him around your new place, don’t tell him the address, he will only come around and try to get you to help him in a collapsed state. My late husband also turned up threatening to kill himself, my son was hiding under a table. Don’t let him come around. Routing for you!! Leave!!!x
