Hi Misssy It almost sounds like when at home its a brother and sister relationship. That's what me and my sister did growing up anything we knew the other didn't like. There are lot's of good things going for the 2 of you. Alcohol is a drug so you are abusing a drug. How do the two of you get along when you both use? It would be great if the two of you could somehow use this problem to bring you closer than ever by supporting, understanding make a commitment with him and then give it time go to a counselor together or AA if it doesn't work out by next year then leave then you will know you did something to work it out. Sometimes we can turn lemons into lemonade.
