My cousin likes my boyfriend. What the hell should I do?

ok what should I do?

My cousin likes my boyfriend and she is constantly hanging out with his family to impress them. My boyfriend can't stand her and doesn't like her, but she is really breaking the relationship with me and his family. She tries to flirt with him and she makes things for his family.

I'm not the only one who sees through her plans other friends see it to. She plays innocent and sweet and acts as if she knows nothing. What do I do?

She was over his house doing zumba with his mom and sister when she knows that me and my friend do zumba with them. She is trying to take over my life she even toke the job I wanted and said that I didn't want it and she rubs it in my face.

Please everyone I need lots of advice. Please share stories if something like this happened to you.
