Help! Does he like mee?

There is this guy i have known for about 2 years now and i really like him and he keeps sending me signals but im not sure what they are supposed to mean. He eats lunch with me instead of his friends, he helps me with homework, i catch him staring at me a lot (we make a lot of eye contact), he is very protective of me, he plays with my hair, he helps me carry my books, we talk to each other A LOT, he stands at my locker and waits for me, he walks me to cl, he always stands close to me and hoovers over me like he if keeping me safe so i dont get hurt and there is ALOT more but i just cant remember i just want to know what he is trying to say.
