I think a guy might like me... help please!?

so I have never really had a serious crush considering I am only 13 but I think I really like this one guy. I have known him since 4th grade and we have had at least 3 classes together each year. This year I have 5 classes with him. He is a fairly shy guy he doesn't talk to people much tan outside his friend group where he acts open and friendly. We talk to each other on I would say a daily basis. I catch him looking at me mostly in every class we have together he will have a little smile on his face sometimes. We take the same art class. In this class, there is music and were allowed to dance if we are in the mood. He barely talks to other people including me since I have known him but since this year started he started talking to me and laughing with me as if I were one of his friends. We made up a dance in the same art class mentioned earlier together and whenever I do silly dances he always laughs. One time in a class building activity in homeroom we were outside and blindfolded. we were supposed to find the person infrot of us and make a conga line. the boy I think I like was behind me and he threaded his fingers through mine on accident I think but I don't know since he didn't immediately remove his hand. I really like him but I don't know if he likes me back. Help pls!!!!
