Answer please help !!!!!!!!!?

okay here's the deal at the beging of the school year i meat this really amazing guy. we ened up daiting and everything was perfect. his family treated me nice and i was really close with alot of his friends. all except for one, we had been best friends since 2nd grade but over the summer he had changed alot. he started acting like a player. he would always say stuff about me not being good enough for my ex and all of this other b.s.! it really got out of hand. one day when we were out by the busses his friend was in a shity mood and he decided to take it out on me. i said something to my ex's mom and she just lost it she said i was jsut trying to come in between there friendsip . to make matters worse she has his myspace pword and she got on and sent me a very harsh break up message. i didn't talk to him for a few days because i thought the message had come from him. i was wronge, i finally decided to confront him and he said that he was sorry that he didn't stop his mom and a bunch of other stuff. we decided to keep daiting behind his mom's back. that worked for about 2 days. she came up to the school and told our princable that we weren't supposed to talk at all. well that is what has been going on for the last month. but thursday i couldn't take it anymore and i went and talked to him anyway. he said he missed me and now we are talking... idk if i should try to have a realtionship with him again or what. we both want to be together but his mom is making my life hell as it is... there is more to the story but i need to get off so i'll finish later but so far what do you think i should do ????
