How to tell...

Emily

Ok so I've been talking to a classmate of mine for a while and I think he likes me. As more than a friend type like. He always goes out of his way to compliment me like my shirt, boots, hair, ear piercings, and even my freckles! He bumps into me a lot too...playfully of course. I have never been able to talk to a guy so easily and we always walk close enough that we are touching. But anyways my real question for this is how to tell if a guy likes you because I'm assuming he does, but I could be wrong.
