scared my friends will be manipulated and turn against me?

[Anj]

We had a group of four. One of the four decided to distance from me and barely contacted Me in the last year. She told my other friends she didnt have time for my "drama". She wants to be my friend now that I dont need her though..funny.

Anyways, iin the last year our mutual friends knew About this fighting and they didnt do anything to get involved which I am grateful for. The other girl tried to act like they are all best friends and happy by posting things on facebook. I can completely tell its all fake though. This girl is really manipulative though. She blatantly manipulated one girl to do stuff for her. im scared that she will get my friends to turn against me. She's been badmouthing me and making herself appear a victim while I have said nothing. I didnt feel I should badmouth her because im not that low. Any advice? These are my two closest girlfriends and I never want to lose them.
