this may be long but I really need help

Okayy, well I met him on his birthday which was on October I think or September. We went out to go for lunch with other peoples. We both were laughing together and we both did a prank on some one to drink water that had salt in it. Well then we didn’t talk after that until my school had a Halloween dance. My friend made him slow dance with me, the second time he wanted to dance with me but, then there was a third time he was made to dance with me. Right before we danced the third time some ask him if he liked me and he said no. After that it was weird but then I got the courage to tell him that I liked him and it came out to be that he liked me 2. Well I need advice I told this boy that I have a crush and he told me he liked me but, that was weeks ago. But, one of my friends ask him if he still liked me he said no, a few days ago he started kind of talking to me like saying hi my name, whats up. Now we don’t talk but we hang around each other well I getting mix signs and now I think he doesn’t like me but I don’t give up because my heart won’t let go. Also he acts nervous around me kind of shy well yesterday I was hiding from my friend that was inside my school and then my crush’s friend came to where I was then said I was there. Then my crush came to where I was but then nothing happened. I don’t know what to do. HELP!! Well yesterday he was suppose to take the other staircase on another side to get to his class but, then he was on the side that I was waiting near the doors holding it for me. I didn’t the mistake I wish I didn’t do well I went through the other doors. He went to the other side to get to his class. He’s class is next to my class for that period we ended up seeing each other right before we enter our classroom. There is something else I forgot to mention well, my close friend said that he touch her hand like one on top of the other he’s hand was on top and her’s hand was on the bottom. Peoples thought that they were dating because they were wearing each others sweaters. Sometimes I think that he trying to get me jealous but I don’t know.
