Boy problems.

So this guy and me have had a thing for about two years. We were friends with benefits for awhile and then I ended it because I met someone else and I wanted more than just sex. Just recently we started taking again and we both agreed that we still have feelings for eachother, and we hungout Friday and he tried to have sex with me... I just found out today that he got a girlfriend on Sunday night and he wants to still be friends. Should I forgive him for being an ass and leading me on? Or should I just push him to the curb and leave him there this time?
