AITA for supporting abortion and telling my boyfriend I'm not ready for a child.

Me(18F) and my boyfriend(18M) discussed what would happen if I get pregnant, and I told him that I'm not ready for a child right now and if I get pregnant, I'd want an abortion. He is against abortion and called me a ''fucking whore'' who should ''get her priorities straight''. He wants a child and says he' ll do anything to force me to keep it. I think about cutting back on sex, but I know he wouldn't like it and, despite the fact that he never been physically violent, I'm scared that he might escalate it to physical. I honestly don't know what to do, I tried to leave and he told me that he'd commit... you know... the ultimate act on his life.

AITA for supporting abortion?

EDIT: The one who sent the ''Reddit Ressource'' to harass me should really be ashamed.
