am I inlove?

Just recently, i have noticed something.... everytime i see this person he really makes me smile with out any reason at all.... every little thing he does gives a meaning to me.... just even giving me hi five... i felt there was an electricity flowing inside my body... but the thing is i have this friend(wherein were not that close) she just confessed to me recently that she likes this guy too.... she really find ways to be close to him and i also secretly find ways to make him stay away from her... hahaha.... but my conscience is hunting me..... i dont know what to do at all.... he is the reason why im not crazy about chris tiu anymore.... i have never imagined it was just that fast and this time i hope there's a progress....
