my friend told the boy I'm dating about my past miscarriage

I'm 17 now but I had a miscarriage at 8.5 weeks when I was 15 after I was assaulted at a party. No one but my parents and my best friend knew and it's been that way since. It was extremely traumatizing and I've been actively trying to recover and start to socialize again for about a year.

I was most scared about dating but one of my friends, the only one who knew about everything that had happened, set me up with a guy I liked and it was going pretty well. We've been on three dates, tonight was our fourth. He picked me up and we went bowling and to dinner and he was so sweet the whole time but on the drive home he told me he didn't think we should go out anymore. I asked why and apparently my friend told him that I willingly got pregnant and then had an abortion. He's pro life, (which I would've ended it with him had I known) and he said he doesn't want to be with someone who would kill their baby.

I know I shouldn't be looking for advice online but I don't see my therapist for another four days and I'm just devastated. I don't know how to talk to him or my friend. I have no idea why she would lie, she knows that's not what happened. I was so excited when I thought I found a nice guy.

This is my first reddit post so I'm sorry if I'm doing anything wrong. I made an account specifically for this.
