Hi, and yes, we all get what you're dealing with. Unfortunately, there is little you can do to "get through to him." You came back based on his promises to change. He hasn't done that--in fact, he's done what alcoholics do when they continue to drink--get worse.
I highly suggest that you start attending Al-Anon. It will help you deal with the "emotions" that you said brought you back. When you get on solid ground with what you want for yourself and your life, you'll be in a better position to make decisions about how you want your future to look. This situation will NOT get better on its own. There are tools such as setting boundaries for yourself in terms of what you will tolerate, and detachment, which can help you to cope with life with an alcoholic. Those aren't great as a long-term solution, but they can help make the present more bearable.
