First post and I'm on mobile.

This might be long.

A couple days ago, my friend flipped. She started ignoring us, and left our group chat. She said (after nobody responded to her), "I guess you all hate me. I'm just going to leave then." I texted to ask if she was ok, but she wouldnt tell me what was wrong. She had also been talking about everyone in the group behind our backs. 

The next day, my friend tried to come up to me in school and pretend like nothing had happened. I ignored her, and she yelled after me.

That day she asked someone to add her back to our group chat, and they did. She starts by saying "I'm sorry I suck guys. I didnt mean to hurt your feelings. I love you." Nobody responded. I thought this was a little manipulative tbh.

She texts me and asks if she can explain. I say sure. She said she wasn't mad at us, but dealing with her own issues. I said fine. Whatever. I told her it sounded like a guilt trip to make us feel bad. Especially since she talked about how much we all hate her. She says she wanted someone to ask if she was ok because we should care about her. I tell her I DID ask if she was ok. She ignores that.

She then says that I attacked her by ignoring her? I said that that was playing the victim card. She yelled at me. I say that I would have offered help if she told me what was wrong, and she says that I "attacked her for needing help." We go back and forth for a little while, until she goes onto the group chat that she was added back into.

She says, "I know I said sorry before, but you guys are clearly still upset."

I respond (in the group chat), "I know I said sorry before, but you guys are clearly still upset = Its ridiculous that you guys are upset"

I called her out for manipulation. I said that she was trying to make our issues seem ridiculous and is trying to get us to apologize to her. She was the one talking about us and ignoring us. It's not fair for her to act like it's our fault for not forgiving her yet. 

She calls me a crappy friend and a "jerk." I call her the same. She says its ridiculous that I keep saying that she's manipulative, and I say that that's what it sounds like. I also add that others think so too. (It is actually true, multiple people told me they agreed.)

A second friend and I kick her out of the group chat again. (We use a messaging app and you can do that). 

Now, about a week later, she texts someone in the group and asks to be added back into the chat. She says that it's not fair that I am keeping her away from her friends, but it wasn't just me. Anyone could add her back, but nobody has.

I've told our group that I'm not interested in letting myself be walked all over, and people seem to agree. I want to cut her off from the group, but her best friend is in the group too and isn't so sure. So, AITA for wanting to cut her off or did she actually do nothing wrong?
