Mixed feelings

There's this boy that I really liked for about 6 months and I would think about him all the time, but these past few days I've started to like someone else. We have most classes together and we talk a lot, plus he makes me laugh (a lot). I'm starting to question if I ever really liked the first boy (maybe even loved) because if I did I wouldn't have fallen for the second. And also we haven't even talked.
