I (19F for simplicity) have a crush on this one girl (17F) I used to date about 2 years ago, let's call her "Emma". Now, I'm certain she doesn't have feelings for me back while we still talk sometimes even though she flirts with me sometimes, and I don't even know if she likes girls. Anyway, it's just a little crush, and I'm in an open relationship so the girlfriend (F18) I have knows about it. I probably won't plan to do anything as Emma isn't even ready for a relationship until she graduates high school, that's why we broke up.

This one girl I also used to date and tried to befriend before I found out she was using me, Audrey (F19) also said I was a bad person for being an adult and liking someone who is still under 18.

She then said it was weird because I was an adult and she wasn't even out of high school, but she also told people that I was "attracted to a high schooler" and making it sound like the girl I liked was a freshman who was only like 15 or something.

So, AITAH for my slight crush on a girl I used to date because she's not even out of high school?
