Should I tell his parents what kind of kid they raised?

I (18F) and my now ex boyfriend (20M) were dating for 7 months. He dumped me for his own reasons (work and school and stuff) and I was gonna drop it there. But I found out I was pregnant and contacted him via mutual friends. We were both freaking out and I told him I was 100% willing to raise the baby on my own since he REALLY didnt want me to have it and I didn't wanna have a father for my kid who loaths the child. My parents were fine with me moving back in and setting up a nursery they're upper middle class so the baby would have everything they need. Well he said there was and I quote "no way I could have a kid and him not be a part of his life because he'd feel too guilty". Anyway I was willing to fight tooth and nail for this baby but my ex convinced me to get an abortion. I didn't wanna do it and i'm not AGAINST abortion but he said the kid didn't deserve a father who was working a lot and a mother who was so young. After back and fourth arguing about it saying I wanted to keep it and if he didn't want it he can leave he convinced me that an abortion was the only was and that we'd "grieve together" and that he "could never leave me after all we've been through" as soon as I got the abortion he left and basically only stayed so I could get rid of the kid and blocked me on everything. Do I tell his parents who are SUPER religious that he pulled that stunt. Do I get someone else to talk to him? What do I do

Let me edit this to answer your questions: his parents aren't the kinda religious to slut shame but they would definitely have a "I cant believe you did this to someone" kind of reaction to him
