I agree with Eightball - glad you are seeing this BEFORE you get entangled in marriage and children. There are men out there who will treat you better than this. You just need to move on from this experience and find those men instead.
I wanted so much to be the problem in my marriage - I tried for an entire year to be that problem. Why? Because then I could fix it myself! Because ultimately we all realize in that little corner of our rational minds that alcoholism is a problem we can't fix for anyone else. Your rational mind brought you to this forum. Listen to it!
So sorry this is happening to you. You are not alone, though! Good luck in your journey.
