2 years ago I dated this girl and things ended because she believed I was immature and needy ( I was). Year later she reaches out to catch up, and by then I was completely over her. We would occasionally have sex when she was in my area for college. She occasionally messages me small talk which I don’t mind, I’m cordial w everyone.

Recently, she’s been bothering me though. She’ll message me if I upload a pic on social media w a best friend saying “who’s your friend” “give him my number”. I ignore it, or reply saying “he’s single, hit him up”. I always act indifferent which bothers her, so she does more often. Snarky remarks if we hang out, desperately wanting a reaction which I will never give. At what point do you actually make it clear that it needs to stop. Idc if we stop fucking, it’s more about her displaying no respect and trying to bother me by stating she wants to fuck my friends
