So there this girl I know failry well. She is already in a stable relationship with someone, however we casually flirt with each other. That is in the sense that we just flirt for fun (at least that is what I think). I don't think we have any intention of dating. Maybe if she broke up with her boyfriend we would date but for now I don't really care that much. Here is my question is it okay to casually flirt with someone that is dating? Also all the other questions above.
