Toxix relationship 😴

So I’ve was in a relationship with this guy for about 2years. We constantly argued the whole time.

He threatened me multiple times , called me stupid,dumb etc. I finally broke up with him and now he constantly calls me and FaceTimes me all day saying he wants me back and he’s sorry & blah blah. He has even shown up to my house since I have broken up with him 🥴.

I just need someone to consult with ...
