I have to agree with what everyone else has said. First and foremost is your safety. It sounded like he had a drinking problem. I don't know a whole lot about alcoholism but I know my ex had that problem and when he quit he had to go too support groups and AA to deal with it so there is something psychologically there if he never got help for it. Are there other family members involved like his parents or siblings that may be able to also talk too him about seeing a therapist?
