lots of guys just like having the feeling of a girl liking them when they have little or no romantic interest in a girl, thats why some guys flirt with a lot of girls, we're not trying to get laid just the attention... if you really like him and want to see how intterested he is ignore him for a while if he starts to show interest try to make sure hes going to make some kind of commitment... if he dosent really care then at least your getting out of a bad situation.
