Does he like me or is he just a jerk?

from the way you typed this question, you seem like you are under 19. Honey, you need to stop analyzing everything and just go with the flow. Stop putting all you energy into thinking about this guy and analyzing. I also think that you shoudnt get your hopes up because he had already liked someone else besides you and now, he likes some other girl besides you. DOnt ever be a chaser. DOnt waste your time with him, and concentrate and exert your energy onto someone or something else. Have fun, life is nOT about stressing over a guy.
