Relationships

My boyfriends ex is bipolar and vindictive she hates him, how do I deal with her immaturity?

They broke up 8 months ago , they had an argument, she was abusive and manipulative and overly sexual to my boyfriend and that made him super uncomfortable because he’s suffered from abuse and she knew that. And she made every little thing sexual according to him. She and I knew each other but never were friends , although I did try but she always kept me at arms length and I never forced anything on her, time goes by after the break up (8 months) I had a slight crush on my now boyfriend and apparently he’s liked me for a long time and we started dating. We kept it private and somehow she found out and asked me directly and all of a sudden she’s treating me like shit. I never held and never will hold anything against her. And now she’s unfollowed me on all social media except from her private account but removed me from following her and I guess it’s her way to lurk and keep tabs on me and what I post. It makes me uncomfortable because I have nothing against her. And it was a sudden 180. I think she may still have feelings for my boyfriend but he says she hates him and that she’s obsessed with him to the point where she’s copying everything about him and stalking his stories and writing mean indirect things about him in her poetry. I’ve never seen this side of her before. And I think she’s going through her hurt in her own way THATS why I don’t want to respond to anything she might try. As immature as she’s been with us. But she’s tried flirting with me way before and has been dating girls left and right and she exchanged dirty messages with my other friend (because my friend told me) and I don’t see why she should still be obsessed with my boyfriend because she seems waaay over him in my opinion. I don’t know. He’s my second boyfriend ever and I’m nervous. I’m fairly new to the dating scene so I honestly don’t know and my anxiety is messing me up. He doesn’t know about her unfollowing me yet and I don't know if I should bring that up to him. What should I do?
