This girl is talking crap on me?? PLEASE HELP!!! 10 POINTS!?

Okay, so there is this girl names Ashleigh. We used to be close. But this whole thing started with a picture that was accidently uploaded to facebook. It was innapropreite, but it was only on there for 3 minutes exactly then I took it off. I deleted it, and said I'm sorry. But my other "best friends" started jumping me, and saying some hurtful things. That led to Ashleigh, Nacie, and Balie to all talk crap about me and make up lies about me. THEN tell there parents. Well the parents got involved and started talking crap about ME and MY MOM. (my mom is very opinionated and straight up) well all of them are talking crap about me. And I've said im sorry and its kinda simmered down. But now Ashleigh still keeps talking bad about me because they all through me under the bus and expect me to come crawling back and begging them to be in the group again, what do I do?!!?! (ashleigh has her days where she is nice to my face, but then the next second she starts giving me snotty looks, and some of the things she says is that im a *****, im 2faced.) I HAVE NEVER TALKED BAD ABOUT THEM EVER SINCE THE WHOLE THING HAS STARTED.
