what can a woman do when she doensn't know when i guy is giving her signs that he is flirting with her. this was a question i had for a while. i really liked this guy and i wasn't sure if he liked me the same way that i liked him, worst, i didn't know if he was flirting with me or was he just being nice to me. what i found out is that if a guys starts being really nice to you but not to other girls, then he is defenetly flirting with your. specially if he start to complement you then you really know he is flirting.
