My husband drink beer every day .sometime two or three can a day i have try to talk to him about this but we end up in a fight so i dont say anything any more sometime his stomach hurt sometime he have alot of loose stool?

His body is reacting to the alcohol and his liver and stomach are going bad which definitely isn't good. The problem here is he isn't listening to you at all and until he, himself, wants help, there wont be much you can do. DRs, medical science, and society can help him but until he admits he has a problem and wants help, all of this is useless, so theres no sense arguing with him as he will only use this as an excuse to drink even more so maybe try ignoring him as this will unusual to him and then when he asks tell him,that if he wants to kill himself then youre having no part of it and youre tired of trying and hopefully that will sink into him. Good luck
