"You should move on, forget about me" translates to:
"You are killing my high. You are in my way. I'd like you to get out of my way. I am going to accomplish that by looking like a saint. I am going to inflate myself by pretending that I am releasing you for your own good. But the truth is, I just want to stretch out and have a drink."
If he is an alcoholic, alcohol is what he wants. Not you.
This is the truth of addiction.
