What do I say?

Tell him straight you want to be with him.

Stop getting drunk to where your memory blackens, second cry very hard, wipe your tears and then cry again, if you already done this then do it again, you must understand love isn't a game, see how ridiculous I sound when I'm playing games, you tell him what how you feel and ask if there's a chance, something tells me he'll be very honest with you, and be prepared for good or bad, it's the way it will work, you can play shrades till your nipples fall off and try to spark what's there or not, but show him you are serious and deeply sorry. If he loves you he will forgive you plain and simple.

Be honest with him -- tell him you really don't remember what happened, and ask him what took place, and why he wants to end it. From there, it could go either way, but if it were me in your position, I'd want to know what I had done.

Maybe he is not really pleased of the way you act when you are drinking. It doesn't matter what you did at this point, it is the past. What matters is that a red flag came up, and its a big warning sign for you and your life. I would attend a few AA meetings, I am not saying that he doesn't care for you, but sometimes we need to care enough about ourselves to leave a situation that we know in our hearts will be harmful. Life is to short for the bullshit! Don't contact him, the best way to get him back is to help yourself right now. If you don't remember what happened then that means that you had a black out. Please do yourself a favor and realize that this is a sign to help yourself right now, and I promise you when you do, all that you love and desire will fall into your lap. I have been there and I can promise you this!

You should find out how he feels about you, is it the same spark he had when you first met, are you still friends with him? I think the best way is if you are still friends then take his game to him and that same day sit down and tell him how you feel.

Keep the nintendo in a safe place in case he does come for it down the road. After two years, it seems ridiculous to end it on a drunken note. I'd be shocked if he didn't come around soon.
