I agree, you need to tell the police. Even if your friend is against abortion, this is your body and your choice. If you want to complete your pregnancy, do so. If you do not, you do not have to. Even if he apologized, rape culture is a dangerous thing, and he could do this again to another woman. It is NOT ok EVER and rapists often do it more than once, ESPECIALLY if they are not reported! Do not make excuses for him!
I am so sorry you are going through this, but be strong, and know that there are people who can help. Decide for yourself if you are going to carry out this pregnancy. Tell the authorites what he did, action really does need to be taken against him. It will ultimately be up to you whether or not you think he should know you are pregnant. He might get violent, he might offer to pay child support or help pay for an abortion. If he wants you to have an abortion and you don't want one, or if you want one and he doesn't want you to do it, remember he never had your CONSENT, and you don't need his for that decision.
