I'm really sorry you feel that way but the truth is, you are dealing with an ill person who himself does not know what he wants in life. Actually, I am wrong there. He does know. He wants alcohol. They may love us and promise castles in the clouds and fairytales, but once we get between them and alcohol, then you really see what is their priority. He was not pretending he loved you. He loved you in the only way he knew. But alcohol is no.1. They love it more they love themselves. The good news is, at least he did not fool you into marrying him. You did not have children with this man. You have plenty of time to rebuild your life, to recover emotionally, and find the love of your life.
Believe me, you can suffer now, or 10 years later, but with an addict, you will suffer. Period.
