Is this rape? Can he be arested? ?

I'm 15 and my boyfriend (age 18) controls my life and how I live it, he forces me to have sex with him repeatedly in different areas when I tell him no. I pass out all the time for hours on end when I do b/c of the abuse. But I love him. I can't explain it, but I need him. I can't tell my parents b/c the said they don't care, I'm "old enough to take care of myself" and all, but I'm scared and I need guidance. I just found out I'm pregnant, and I haven't told anyone, I am thinking about going to get a abortion, b/c I dont want my baby around my abusive bf, and I'm in HS. what to do????
