"I love you but I'm not in love with you" is a key phrase you'll see in any infidelity website or book. It's a classic rationalization and is separate from alcoholism. I heard those same words and didn't really understand them. I thought it meant I needed to try harder. Now I think it means--I love you, but I've chosen not to be "in love" with you or try anymore. It's a choice. And those words sound good because they make it sound like he's a good guy while he's rationalizing away unfair behavior.
I do believe he doesn't love himself. That part is probably true. And he sounds honest that he doesn't really want to fix the addiction either.
It appears that he has convinced himself he wants to drink and not be accountable to you...and that it's okay. Thankfully he is at least saying the words.
The hard part is what you do with it. I'm so sorry.
Sending you hugs. You're worth so much more than what he is able to give.
