I am so sorry for your predicament Emilie. Your bf sounds like an alcoholic. When someone is addicted to alcohol, drugs or whatever, there is NOTHING more important to them than getting their fix. It does not matter how much he loves you, he is addicted, and once the drinking starts there is no room for rational thinking.

His behavior will likely continue to get worse, even if he gives you a good day or two. He will go right back to his addiction. Insist that he get help and go into rehab. This is a very bad environment for your daughter as well. I'm sorry but you may have to ask him to leave. The addict is usually counting on their spouse to put up with them. Be smart and get out while you still have time to meet someone else.
