Im new to this forum, and i looked through quite a few threads that had some releveance to my problem but i would like some personal advice...

I'm 17 and i've been with my girlfriend for 4 months...
Everything was going great, and we both seemed perfectly happy, but in the past month and a half she has been accusing me of cheating on her atleast every 2 weeks if nto more. Anytime i dont answer the phone, call her back, or reply to her text messages within 5 minutes, she automaticaly assumes i was with another girl, she thinks im trying to have sex with her best friend who is 13 (i might date younger than me but not that much). Me and her dated about 2 years ago, and it lasted for about 3 months before she decided she wanted to get back with her ex boyfriend. I know shes insecure and self concious, and i make sure that any time he feels bad i explain to her just how much she means to me and how beautiful she really is, but then she accuses me of lieing to make her feel better. She seems to have major trust issues because of her previous relationships.

Now onto what confuses me. Anytime i talk to a female, whether it be asking for a lighter from a stranger, or contacting an old friend on myspace, she hinks im trying to cheat, even when i make it known i spoke/messaged the person. 3 days ago she exploded and accused me of cheatin on her because my father left a brush in my car... I understand it looked suspicious, but the brush was full of grey hair... come on. Then later that night she went to hang out with her ex boyfriend who she had dated on and off for the past 2 years. I thought it was odd but i didnt say anything, because i trust her enough to know she wouldnt cheat on me, but then she got extremely defensive about how they didnt do anything and how she slapped him for touching her leg, again odd but i thought nothing of it. In between the brush incident and her hanging with her ex, i contacted her best freind via yahoo messenger because my girlfriend refused to speak with me, and i asked her freind to talk to her and see what was bothering her... and because of that, im cheating on her....

because of her past i cant blame her for having trust issues, but this is getting too extreme, i really care about this girl, and i dont wanna break up with her, but i cant take all of this drama...

Do you guys think theres anything i can do to fix the situation? Or should I break up with her and hope in time she can learn to trust me?
