He tampered with my birth control and now I'm pregnant

I believe someone I recently was dating tampered with my birth control and I am now pregnant. I feel conflicted as to if I should keep the baby or not. I do not want anything to do with this guy- he was possessive, controlling,jealous, and date raped me. I said no, and he didn't listen. After this I realized things were seriously wrong and blocked him and discontinued speaking with him. Only to find out I am now pregnant.

I have been leaning towards an abortion but keep feeling a sense of guilt/fear. I cant stand the guy, but also, this fetus could grow into a beautiful child. I have never been pregnant before, and this being my first time i feel so conflicted/violated. I feel like my choice to be intentional about having a pregnancy was stolen from me.  Any advice?
