I (16F) am very close with my friends and we all attend a small school so everybody knows each other. I have a couple people there who I used to be friends with but no longer talk to. Theres this girl that Ive been flirting with and shes been flirting back, but the thing is, shes the ex of a person I do not talk to anymore (who is still in love with her ex, mind you.) All of my current friends still talk to her. I got told I was in the wrong for going for this girl knowing that her ex and all my friends are very close. AITA?
