You've gotten quite a bit of good info already. I just wanted to add for this question:
Even if he does like you, even if he is over-the-moon, head-over-heels, thinks-you-hung-the-stars in love with you, *this* is how he behaves. *This* is how he treats you. Is *this* what YOU want?

And I'm not talking about: If he changes. Not: If he stops drinking or using. Not: If he goes to AA. Not: When he's nice. Him. As he is now. As he's shown you he is: the swings between hurting you and pretending it didn't happen (or matter.) Is that what you want?

I'm not asking you to write it out here, but something to think about. Though, if you do want to talk it through, please know we're here to listen and lend support.
