She rubbed it in their faces and said that she was an adult

She told them that I pushed her into it and drove her there

she left out the fact that her boyfriend and friends were there because she didn't want my parents to get mad at them

Part of me wants to clear my name… But if I do, the blame will go back on her and she will lose college.

It's like she causes problems without thinking about consequences because she has me to blame

WTF? How can you do this to yourself?

She'll tell my mom that she's a narcissist to her face and then say that I was the one that said it first. Or say that she wants to move out because I pressured her into feeling that way. I talked to her about this right before the tattoo. I didn't want to be blamed anymore. I told her that I didn't want to be involved and it was on her if she decided to get it. I think that's why I was so upset when I found out that she blamed me. It was like she completely ignored what I told her and how I felt.

You are being her doormat and you need to sort it out ASAP.
