Am I Realy In Love?

Ok, so, there are these two guys in my class. One i have recently dated and it didnt go so well, we lasted a week, and now we dont talk to each other one little bit, ive still liked him alot, but since there is a new guy in our class, i am starting to forget about him. The new kid is kinda short but who cares! I like him, hes sweet and everything, and it feels all weird between us. I realy truly like him and when ever i think about him i get these fantasies going through my head. Am i in love with him? I cant tell, please help, comment what u think, but please no hatful comments.
