Girl who is very attractive I have been flirting with keeps texting even after I go cold for a few days. She is seeing another guy. I get the vibe he is a nice enough guy but I get the sense she is seeing him because friends set them up. She is clearly out of his league and she clearly knows it deep down. She texted back to me yesterday after a week of no contact from me. I was considering send her back another flirty text but with a quip along the line of "we shouldn't keep texting though! Clearly you are being swept off your feet by xxxx. We don't want to make him jealous". Valid strategy to build attraction? Anything else to neg him subversively?
