Toxic relationship !

I been with him for almost two years now and he showed his true color couple months back he calls me ugly names like whore , bitch, SMI, all of that and It hurts me and apart of me just wants to leave so badly but what we had and been through stops me from doing it idk why😐 how can I get the courage to leave this disrespectful boy without feeling like I need him when I fucking don’t need him! He always tells me he doesn’t want to be with me but always comes right back to me and right now I might be pregnant with his baby idk what to do this is my first ever relationship 🥺
