Just have to not like him anymore

It's like this. someone just confessed that he actually liked me, though I didn't believe him. Cause it's actually impossible for one to like me. I'm a nerdy ugly innocent? girl. And so, I told him that it was just an infatuation.
But on the days that were coming, i thought I'm beginning to like him. And when I've already admitted to mysef that I do like him, I sensed that he was flirting with another girl. I freaked out cause the girl that he's liking now is actually the girl whom I've shared something. A little secret. That he liked me. And now, he likes her. Haha. I just felt irritated at first, but then I realized that...whatever. I don't need a guy right now anyway, and he's such a playboy. Though now, he's sitting right next to me and i can smell him. SO SWEET. ahhahaha.... urg! I can't like him! Urgh.
