Does alcohol make you lazy to persue a relationship?

My bf (57) and I (50) have issues because he doesn’t try to see me much. He admitted last night it’s because he’s lazy. I thought it was because he wants to drink locally but maybe he doesn’t really love me like he says he does. He calls constantly but usually when he’s drunk. He’s admitted to being shy. My question is, is he lazy because of addiction or because he doesn’t love me (enough)
