Forced abortion?

I am on bc because of my partner. He ejaculates inside. Months before him doing that he stated "jokingly" that if I became pregnant he'd push me down the stairs. He doesn't want biological children and is getting a vasectomy sometime this year. He still ejaculates inside and has me "push" it out, as if that's going to help. I take my pills regularly so I don't get pregnant however he is telling me that if I get pregnant, I would have to abort it. As if I don't have a say in the matter. I'm afraid that if I do end up getting pregnant. He is going to force me to have an abortion. Whether it be medically cause or physical force. So I'm wondering if I should tell him at all if an oops were to happen? And if it does happen, I can't be forced to have an abortion, right?
