One of my best friends always flirts with me and makes it apparent to other people too. Sometimes he says something flirty or grabs/smacks my ass. But to be honest idk how to feel about tht because I used to have a crush on him last year but he didn’t seem interested so I stopped trying but now I think he might like me but idk wat it is but I’m not as interested as I used to be I still like him but I moved on and now I guess I only see him as a best friend. What should I do?
