From the other side of the fence.
I used to be the alcoholic boyfriend of a few different young ladies (when I was younger of course)
And I am serious when I say... Go and stay gone.
Your alcoholic in denial boyfriend is a mentally sick puppy, he will be a tornado in your life, that will see you eventually end up as sick as he is.
You can't fix him and he does not love you like you love him.
Ignore everything that comes out of his mouth with regards to "love".... Actions speak louder than words.
Always watch his actions if you want to really know how he feels about you.
