I really picked a winner🙄😒

Sorry Ladies.. I just needs to vint 
My ex and I have not been on talking terms. And I'm ok with that.. he is a very toxic person.
But every month or so he ask to meet up to talk.. (we've already talked about this same question 7 times before) so here I am meeting him at a public place and give me the impression that it will be a different conversation. 
I'm am 19 WKs nows. And he has been nothing but pro choice since he found out I was pregnant. So all he ends up saying to me is "why doesn't he get an opinion about this pregnancy?" 
At this point I'm soooo tired of this question being the only question he has for me. I'm a single mother of two kids already.. we where together for four years.. I was the only one taking precaution with taking the birth control pill.. he raw dogged it the whole time... I told him... his option would have to also used a condom and now that I'm exspecting, his opinion doesn't matter because it's my body.. period. He's made it clear this is something he doesn't want. He wants this "problem" gone.
Like I said I'm a single parent already, and LOVE  every bit of it! I told him he can leave, sign over his rights if he feels like his life is ending, I won't come looking for him, or hold him accountable.. because what I can't do is deal with this negativity amore.
He still asking me to get an abortion. Because I know he's so ignorant to the subject matter I do feel like I should send him some Abrotion videos of exactly what he's asking me to do. I just need this to stop.. or get him to realize it's not going to happen. I'm a high risk pregnancy and he knows that and I feel like if anything he's trying to stress me out and bully me so that something does happen to the baby.
I'm very discussed in him because this is not the man I was dating.. and sadly this is his true colors are showing now. Please let me know of any suggestions.. or measures I should take.
