Welcome to SR starangel. Sorry to hear of the issues you are dealing with regarding your BFs drinking. As Dee mentions, there's really not much you can do to control or chance another persons drinking, especially if they are an alcohilc. We can't say for sure if your BF is or not, but he does have many of the telltale red flags, and his drinking is hurting you in many ways.
Unfortunately some addicts will choose their drug of choice even when confronted with losing very important things....you will need to prepare yourself for that possibility. It's got nothing to do with you, even if he says it does. We do have a special forum here for friends and family of alcoholics as well where you can meet and get support from others who have been through what you are experiencing. Stay safe and take care of yourself.
