Gushing about a Crush! What Should I do?!

I have a crush on this guy who I met at our schools drama club. I joined costumes and he is on set crew. last December we had our first show and I didn't have much to do. the play was created by one of the directors and it was manly based from current events so actors just wore what they usually wear or what thier characters personality is. basically costumes crew had nothing to do. same with set. they built one big platform and that's about it. The guy I liked was majorly involved in doing a spot light during one of the scenes so he was up where I would hang out. more like the other way around but you get the point. we became closer and closer. he even sat next to me during one of the shows when he could have sat somewhere else. then the show ended. I fell from great heights and then hardly saw him. the wierd thing is, after the play he started coming into one of my study halls for no other reason than to talk to his friend, or a teacher about nothing, or just stroll in cause his woodshop teacher would let him. he never came in before that. I thought it was an excuse to see me but I haven't gotten anything more than that. I mean he sat next to me once in the study hall and did some work while his friend sat another table ( for being disruptive ). there was another time where him and his friend where walking g down the hallway after school with me and earlier his friend, (let's call him Greg) who is also friends with me and is the same friend from study hall, where trying to come up with my Nick name cause earlier Greg was trying to be funny and saying my name wrong. in the hallway it went from Amelia Apron, to Amelia Airheart Rose the III. The butterflies in my stomach where going Everytime he said my name. I had a plan for all of us to get pizza so I could spend more time with him, but it never worked. most recently our spring musical happened. it was Pippin. He said he wouldn't be able to do it because he had baseball. but low and behold, he was there opening night. both of us had work to do but we made time to hang out. I luckily had to hang out backstage and help with quick changes so I was sorta hanging out with the entire set crew. opening night the only interaction that was pretty memorable was when I was filming and he got in front of the camera and started dancing. the next day was even better. we had two shows that day. we would have alot of interactions most of the time with just each other. Anytime I would sit next to him he wouldn't move away to find another seat or like pretend to see another person and sit over there. we would always be sitting next to each other. I will not forget the moment when we where backstage during a scene where Pippin and Cathrine are singing to each other and him and I where behind a platform standing next to each other. he had to push it out later in the scene so he was preparing himself. we where goofing off ealrier with a retractable blade prop and dancing along to whatever song in the dumbest and funniest way. when we where standing in between the platform and the wall I had rested my arms on the top of it and then my head tilted so the top of my head was in his direction. he stood there just nothing. doing his job I guess. I wonder if he even looked at me or tough about touching my hair. ughhhhhhhhhhhhhhhh. I had touched his hair, spiked up from the heat of the room. I also touched his face. the whole set had to get some sort of black shape on thier face and he had a triangle that was melting. I didn't expect him to ask me to fix it, but I did with my finger. it only made it worse but he oddly didn't seem to care after asking me to fix it. my main delema is, am I waisting my time or am I just impaintent? cause I am very worried about losing another crush to me not being able to see them for a long time. I'm just very anxious. I just don't know what to do with myself. just tell me anything you got from this.
