Does my crush like me or is he playing mind games with me?

Ok so I've had a crush on this sophomore (I'm a freshman) for a couple months now and before I noticed him a lot I would purposefully make us cross paths but since I've backed off of him almost completely ignoring him he has made eye contact with me more, smiled at me, held doors open for me, and a lot of other things as well so what do I do?
