I can't tell if he likes me!!!?

This is weird in a confusing way but a guy in my spanish class has been locking eyes with me. i've had a crush before ,well still kinda do but we've made eye contact and holding it for a few minutes. And there was a day when my friend said my hair was pretty He turned around and made a small smile. and at school our homebase classes are right across fom each other and i sit right next to the door and he does to so i see he every morning and we make eye contact. But the bad part about this is...... HE'S DATING SOMEONE ELSE!!!!
