What do i do? Am i a bad friend?

ok. So here's the story. (all names have been changed) a month ago I reported this girl who has been bullying me for 3 years. It was hard to do but i couldn't live with it anymore. So anyways i reported ashley and i tried to deal. But my bestie aoife had helped her. I was hurt and betrayed when i saw her do that on the cameras. I didn't talk to aoife for a week. until the councillor brought us both in and made us. As usual aoife did nothing wrong and the cameras were wrong. As usual i stupidily forgave her. Barely two hours later she made it obvious she wanted to be friends with ashley even if that ment we couldn't be friends (even though ashley had dumped her half a year ago for going out with jerermey and although ashley and her friend natalie had been horrid to me i had stuck by aoife) aoife knew i needed her and she just dumped me. That friday my other friends ella and matt (jermeys bestie and my other bestie) were in the car for a spin and a chat (their in different schools so i only see them on the weekend). I told them the story and matt told me aoife was telling everyone i abandoned her! he said i was obvious that i didn't because she just went back to her old friends but still! 
Well its a month and a half later and i'm dealing with it but i feel horrible for having matt in an awkward situation with me and jermey because jermey blames me and i keep bursting into tears around aoife. 
What do i do? (and i should probs mention that i really like matt as more then a friend so i want the best for him but thinking about losing him makes my heart hurt :/)
