should I stay with my terrible boyfriend?

Should I (F27) stay or should I go(M30)??

We’ve been dating for 3 years now. He has done just about everything but cheat on me. No support. Flirted with other women IN MY FACE. Talked shit about me to his friends and family. Effortlessly not kept his word and honored his commitment with me but will put on a cape and fly across the world for others. Has terrible communication skills. IS FILTHY. No help around the house. No support when I was depressed but I was with him every step of the way when he has depressive episodes due to his BiPD.

I could go on for days.

He’s not a bad person. And this is his first relationship.

Since May he made me a promise that he will be better and he has been. But after two and a half years and you knew I was going to leave??

I feel like I know the answer to my own question. But what do you guys think? Stay or go?

TLDR: should I stay with my terrible boyfriend?
