newlywed... how far is too far?

Tweet

I have been married two months, yes two months and as soon as I said 'I do' he changed... He went from being my absolute perfect man to being jealous, insecure and an alcoholic. I can't take him out in company because he embarrasses me. He accused every guy at a party at the neighbour's house, who were all married, of hitting on me. We had to leave a concert early because he got mad when I asked him to stop drinking so fast, which he asked me to do anyway, because I knew we would end up fighting. Which we did anyway so basically a no win situation. I am trying to wipe the slate clean, forget this and start again with him but i'm finding it hard to forgive his behavior so that we can move on. I have also banned all drinking because I know that this is the instigator but having an alcoholic father I know that he needs to want to change and he admits that he misses drinking. Will he ever change or am I stuck with this behavior? Are these faults I should 'accept' as part of the compromise or should I be making a stand? Are there any groups I can go to for support? I live in North Carolina. How much of this do I have to take to be able to say i've given it my best? I am at my wits end. Please help.
