LADIES & GENTS: I NEED SOME ADVICE PLEASE..? :[?

My boyfriend of 18 months calls me every name in the book. , *****, ****, ect. He makes me so stressed all the time. I have a really bad hair pulling problem now because of the stress and I'm bald in some spots and he makes fun of me saying I'll need a wig in a few years. He tells me that he will have with any girl he wants and that if I ever cheat on him he will punch me in the face. and he thinks that he respects me.... That's not respect.... I know you're all going to tell me to leave him but really what do you think of this ?! I'd like to know..
