Two things stand out to me in your post. Yeah he needs to get evaluated about his drinking issues, this is heading down the wrong road, at least right now. Maybe they can be fixed. The other thing is you said you've never been so happy in the last year since you've been with him, yet you make it a point to go out with a guy "friend" to a club and this "friend" has interests in you and you don't understand why your b/f doesn't like it? Is that any way to treat him, sounds unappreciative and on the playing games side to me. Let's not confuse these two separate issues as one doesn't justify the other. He should not be doing what he is, drinking or not. It also shows me that you didn't respect him or yourself much to do what you did. If he really means as much as you say to you, help him get some guidance with his drinking and explore within yourself how important he really is and how you would like to be treated in the same scenario. Keep talking with him and set boundries and follow up daily to make sure he has plans to see someone about his drinking. I hope it all works out for you and you have another great year of feeling good.
