what do i do?!

I have a crush on my bff's bf. I get one text from him and I can't help but smile all day. I feel alone everywhere but with him. currently he's mad at me and when he gets mad he completely cuts all ties but I at least wanna be friends. I can't stand him hating me. ik he's bad for me... tried to force me into sending nudes once (long time ago)... anyways how do I make it stop 😭?!
