Even if a girl does have a boyfriend don't just bail on her because you can't see yourself getting laid. I was chatting to some girls one night and my target had a boyfriend (I didn't find out until he called her while we were chatting). While she was out on the phone to her boyfriend I had a nice chat with her friends. When she came back we continued chatting like nothing had happened. Don't dispair if they aren't single.
So what that I didn't take her home that night? I ended up having a few laughs with her and had some deep/personal conversations with her. I don't feel that it was a wasted effort at all. Why should you?
At the end of the day, pickup is all about self improvement and having a good time, if that is all that you have achieved at the end of a night then you are on track.
