Regret after letting my ex partner pressure me into a abortion

I don’t really know if I have a right to feel so heartbroken from something I did myself?

So I found out I was pregnant after my ex partner had left me 2 week prior. He was so abusive when I told him and he had bullied me into having the abortion. He wore me down and I had the abortion Thursday. He promised he would support me, but on the day he was no where to be seen, and I’ve not heard from him since. I knew it wasn’t what I wanted and I wish I had been stronger and said no. How do you carry on knowing you’ve made the wrong decision and make this pain go away?

I lost my baby last year at 14 weeks, which just makes this so much worse. I feel like a terrible person.

Sorry to rant, I have no body else to talk to.
