There is a boy in my grade and maybe 2 months ago almost the whole grade thought he had a crush on me. One time he even told me he had a small crush on me. Lately though he hasn't been talking to me and I saw him hanging out with a girl at a basketball game. I don't know if he is trying to make me jealous or if he just really doesn't like me. It won't really effect me either way but I would like some advice on how to tell whether someone would have a crush on me for next time it would come around. Thank you!! :)
