I need opinions

When I was with my ex there was a few instances when I was uncomfortable with sex and at those he respected me. There however was a time he didn’t, he tried to get me to have sex and I started to cry, he tried comforting me for all of 30 seconds before trying put his hand between my legs. I told him I didn’t want to and he said that sex is important to a relationship. (Although I think this is true it is not everything!) He just kept asking me over and over again to have sex with him, I still didn’t say yes but he pushed me down in the bed and did it anyway. I know this is rape and honestly my body just froze up. I disclosed to my best friend and she said it’s not rape because he was my boyfriend🙄 now I’m pregnant with his child and I really don’t want him around or involved in mine or the babies life, is this f*cked up of me?
