My alcoholic boyfriend asked me to marry him and I said yes

We have had endless problems and fights because of his addiction that would make him snap at me often and get mad for no reason.

He does a lot for me and I don't think anyone has ever loved me the way he does. I just have problems with his alcohol and him not taking good care of himself and his health.

What I'm most certain about is that I love this man more than anything. I'm just worried about the future. He says he is trying to stop and get sober but I really don't see any progress especially that we are in a long distance relationship so I'm not with him on a daily basis.

When he asked me to marry him, I just though of him as the love of my life and I couldn't say no. I wanna be there with him and help but I'm scared that that will affect me as well as sometimes I get very sad and I cry when we fight or things go wrong.

Any advice?
