I don't want to fall back into bad habits with him. easy 10 points!?

drop him like a hot pancake girl!, this guy is a LOSER!, he is using you to get whatever he wants, and it sounds to me like he has a pretty bad track record altogether in the relationship dept. your nothing more to him than a call, (he called you @ 1am?,). i think he only cares for himself, dont let yourself be used, and treated like that. i wouldnt waste another minute on his a**... i know its hard to hear, but you have to look out for yourself. somewhere in this big world there is a man that will treat you with the respect you deserve. good luck to you!
