‘Friend’ jokes about stealing my boyfriends?

I’ve got this ‘friend’ who always seems to want every guy I have. She is dating my ex currently, and she said she was sorry. I was extremely angry at her because she did it behind my back and lied to me about it. She also rubs it in my face constantly. She ‘jokes’ about ‘stealing’ my new current boyfriend, even though she’s dating my ex. She says it’s a joke, but I do not trust her. What is wrong with her? I can’t unfriend her because she’s part of a larger circle of friends.
