He wants to break up if I got pregnant ๐Ÿ’”๐Ÿ˜”

He knows that I'm against abortion. Then we had this talk about what if I got pregnant and he just said he would break up with me if I got pregnant because I don't want to have an abortion.

I told him if I did get pregnant and he left me I would still keep the baby because it's my baby. Then he said it's 50% of my genes why can't I have a say about it?

He said that the baby will ruin our future since I'm doing medical degree and I'll ruin his because he'll have to pay for child support.

He said he was never worried with any other sexual partner because if something goes wrong they would abort the baby.

I'm 19 and he's 21.

Now he's telling me he doesn't really want to have sex with me because it stresses him out each time we do it.

Thoughts?

I talked to him the day after and he wouldn't answer my phone calls and left me on read. Am I overreacting?
