Abusive relationship...

Been with him for almost 2 years, recently almost gave him 2 grand to pay off his debt with his ex so we can move in together and tonight he misworded something and i got very upset and he kept cursing at me and i talked to him about cursing before at me and he promised it’ll stop it’ll stop it’ll stop it NEVER does. Tonight he kept saying “bitch bitch you’re a fucking bitch” and I started crying because he was calling me names and then I took him home and he showed me the middle finger and left my car and that just about did it for me. This is the man I prayed to God that I could get pregnant with, a apartment and much more... I don’t know any other girl out there that will pay off your credit so y’all can live together (2 grand) even after cursing at them constantly. He doesn’t even TRY. One disagreement im a dumb bitch. I love him and all and i blocked him on facebook because I couldn’t take the pain and put single now he’s blowing up my phone saying it’s wrong to put single and etc and calling me etc and I’m ignoring it. Help please... I dont know what to do. I been insecure my whole life and this is topping it. I hate my life.
