Please I need advice

I’m not sure if I’m in the correct group for this, but I recently found out I’m pregnant and I’m about 9 weeks and 2 days,ever since I told my significant other that I’m pregnant he has been distant and he just told me he hasn’t been happy since I told him I was pregnant. We have an almost two year old, he has 4 kids with this horrible person, and he’s telling me he does not want this kid, I told him I’m not comfortable killing this baby, I have post partum depression from my first child, and I know getting rid of this baby will put me in darkness. I don’t know what to do, I don’t know who to talk to, he’s telling me I’ve made the wrong decision, he doesn’t want me to tell my parents but I already have, I can’t even enjoy this pregnancy because of him.
