I have been getting this response a lot lately -

Now granted some girls could be telling the truth but I think we all know that some girls will just say that to shoo a guy away...

I learned that if you get this response then you ask his name and if she hesitates that means she's making it up - If you catch her lying about it have you guys ever been able to turn it around? In the few instances that I've caught her and called her on it she didn't change her mind about me, she just basically told me to 'piss off'

I guess my main question is - Even if she is lying when she says 'I have a boyfriend' is it best to just move on?
