Whats his situation now kate? Dont give up on him, theres no greater love than the love for you children. Some people just get in a really bad rut and its so hard to get out of it. I told my mum everything she was crying her eyes out and worrys about me alot.
This is just a suggestion.. but i dnt know how bad he is… what if you tell him to get anger councilling and drug and come back yours and only if he is willing to do it all and want to quit. But i dont know how bad he is at home. So thats up 2 u. Sit him down tell him its breaking u and u dont want to see out bad happen to him.. good luck
