I’m so confused

So just recently i started talking back to my ex, and everything was going good and so Monday and Wednesday we had Sex unprotected and i know we shouldn’t have, but once again i was fooled by words and didn’t go by actions! And now that we both think i could be pregnant he’s telling me i have to get an abortion and he’s been distant i really hate myself! I just feel like I’ll never be treated the way i deserve to be, I’m already raising kids on my own and i just wanna give up
