(Picture are used for representation purpose only) Ask him: Now, this is an assessment every girl has to make on her own. What if the man who comes across as a flirt is serious about her? There are times when guys who don't know how to deal with a proper relationship drop hints that seem like flirting. If a modern-day girl senses that – and she likes the guy minus his flirtatious streak of course – she must do some background check on the chap (that is not difficult) and also keep an eye on how he talks to other girls. If she is convinced that she is the chosen one, she can ask him why he has singled her out and not others. Once he answers – if he is serious, he will be very awkward -- the girl will automatically know what to tell him. One response could be, "If you wish to impress me, stop this nonsense."
