It only makes it harder to love a guy who probably, and perhaps; barely knows you exist. But, personally, I believe that just a simple 'hi' would do. Try sending a cute text or a least a smiley to the guy you like. However, if he has a girl; I suggest that it is not worth the drama to split the couple up for your own personal gain. But, if he decides to put you down harshly, then that is clearly his loss.
