I really need help with my ex!?

Okay my ex recently he confessed to me that he still likes me so we were talking on myspace and he called my phone and my mom picked up ( my mom doesn't not like him because i told her that him and his ex went back together, when they didn't because my friends told me they were flirting and kissing each other blah blah) so he sent me a message saying "i called your phone and your mom answered im so sorry, tell her im really sorry". so i asked my mom what she said to him and she told me she said dont call my phone anymore. So i called him and i was like what did you say and he said all i said was hello..or something idk...so i was like my mom does not like you and he said i know and my mom took the phone and asked him why dont you think i like you blah blah....she told him that " I dont want you talking to my daughter because you broke up with her and went back out with your ex...and dont want you playing with my daughters emotions" and he was like im not playing with her emotions and me and my ex dont go out"....to make a long story short i was like so do you have anything to say and he was silent then he said "i feel bad" and i was like you should and he was like why and i was like because your lying and he started to raise his voice saying how am i lying...and i was like dont raise your voice at me...maybe your not lying but your not telling me the whole truth and he was silent for a few seconds and i was like am i right...he was still silent and he told me that him and his ex started talking and she started telling people that they go out and people would come up to him saying you too go out and he'd be like no we dont..so i was like okay tell that to my mom and i walked out the room and i came back i asked her what she said to him and she was like i told him you too cant date but you too can be friends. I was so upset!!! I was like why did you say that and she was like you said that you saw him and his ex kissing and i was like no i didnt my friends did. and she was like oh well...(it's like she doesn't care) and was like can you think about it and she was like you need to get yourself together before you have a boyfriend she said that i need to change attitude amd blah blah...soooo i went on myspace and he wrote: your mom does not like me and i completely understand dat i jus dnt wnt to mess up anything else so she said dat she dnt wnt me datin u anymore so i meen if u still wanna call and tlk we can but i have to follow yor mothers rules im not gon disrespect her rules...and i wrote to him : Yeah i understand..yeah i still want to talk to you..i talked to my mom and she said she'll think about it...i guess she's okay with you because everything is on me now..she's saying i have to get my self together...like my attitude and blah blah...so i guess i need to step it lol....all he did was read it he didnt reply back...maybe because he has basketball practice idk but he was acting a little weird at school and i was like why are you nervous and he was like im not (his ex was there and she follows him everywhere) idk maybe im just over thinking things...but im really stressed right now because i tried so hard to get back together with him and now everything is falling apart i dont know what to do.how can i get everything back to the way it was..please no negative comments....
