I want to know if this 14 year old guy likes me...?

Well, He hangs out with me as much as possible. we talk during homeroom, channel 1, between periods, ( He has the locker beside me) And while walking to buses. When we are talking he always has eye contact with me. Plus he is always teasing me in a nice way. Also, when half of the 8th grade was gone on a field trip, he sat on the empty side of the room. He asked me to sit with him during lunch. I have to know if he likes me!
