Sometimes I'd be doing all the right things when talking to a girl. Being funny, flirty, and interesting, etc. It's usually positively received, but the flirting feels very one-way. At this point I figure she's either not single or not interested. The way I see it, if she's not interested after 15 or so minutes of talking to her, it's probably best to move on. If she's interested but has a bf, it's probably best to gauge whether she's in a shitty relationship and she's willing to jump to the next available guy. Anyone know how to tell which situation you're in?

easy solution brother,

When in a set and she is interested after a few of your best lines or after a couple minutes just say 'I bet your boyfriend is jealous we're talking' or something along those lines. If she doesn't have a bf she will say, just reply with 'Oh... I just assumed as I thought a woman of your beauty would be taken' That usually will get her to then give you a reason or she will just shyly smile but everyone is different.

If she isn't interested in you after you've opened or after a few minutes well what does it matter if she is taken or not? Your set isn't going anywhere and move on.

If she has a bf but is interested in you and what you have to say then be he friend, build more rapport and let her know your there if she needs you. You don't class it as a close but you'll make a good friend that will give you social proof if you see her out and its just always great to have female friends, most of my female friends have bf's and I respected that.

I hope I've helped bud, if you wanted to watch material on it look at AFC Adam's 21 con stuff that's what helped me when I had this problem.
