Welcome!
Hey Lil,
Welcome to SR! This place is full of people growing and supporting one another. Read the books, it took me a few times of reading Codependent No More, before I really understood it, but well worth the time.
Be gentle with yourself and put yourself first, you said that you just want hiim to know what he's losing. My guess is he already knows but in my opinion, alcoholics are not the types to pour out emotion, they prefer to drink any pain away. Fortunately we don't have to do that!
Someone here told me to stop trying to make sense of an alcoholic mind, you possibly understand their thinking. Once I figured out that they don't have the need to communicate emotion, they drink it away instead, it really helped me.
Best of luck to you and hope to see ya back!
Hugs,
