I'm not talking about a ONS, more like a girl who's actually dateable. We've hung out a couple times, but now I don't know whether to waste my time or not. I've seen people say not to acknowledge the bf, just meet up every once in a while and escalate, or otherwise say the bf is a "nice guy" or something like that. I have also seen people say to just tell her that I don't have too much time to spare for women I'm not dating or to tell her when she's sick of him to contact me. Both seem like opposite tactics. What is the final word on which way to go?
