Friend troubles

So I have a friend we will call her TLF.We used to get on great but then I started to think the worst thing I ever did was put her in the group chat with my other friends. She turned into a straight up bitch. We got into a fight and all 3 of my other friends were on my side. I felt bad so I said sorry and stuff. But I was still serious about what I said in the fight. I lied about nothing. I told her numerous times in the texts that I didn't want to be friends anymore and she said it too. I guess she was lying cause the next thing you know she is back in the friend group. I shrugged and just moved on in life. But I have been out of town all summer and all of the sudden TLF and another friend CW started sending snaps to the group chat of themselves hanging out and having a good time. They were sending them to the chat that consisted of all our friends. I asked them to please stop because if you don't envite everyone to your sleepover then don't post it in the group of all the friends u didn't invite. After I asked nicely they both just kept going and wouldn't stop. I started to sound a little needy because I missed them so much and haven't seen them in a long time and I guess it just fueled both of them more. I ended the fight and refused to respond till the morning. I am just sad because CW used to be my good friend and all of the sudden she wasn't. She is a traitor. TLF is no better. I've heared CW say many times that TLF will do anything to be in the popular group and she will. Now TLF sends snap after snap to the group and all of her pictures are of course, putting her in the best light and making her look good and all sexy and of course she dyed her hair and of course it has to look amazing. 😂 but ever since the fight it has been so tense. I hate her. I hate her for stealing my friends but I guess if my friend left she wasn't a good friend anyway. But I'm scared to send anything funny or remotely inappropriate like I used to be with them. It used to be so fun. But I'm scared she will somehow

use what I say against me or send to guys. I just don't know what to do. I just want to go home and feel like I have friends again. I would send pics of the fight but it tells them if you screen shot on snapchat. And the fight before was too long ago. Any advice for me?
