Advice on my crush please? (major boy drama)

Ok so heres how it all went down:
There's this popular boy at my school and I never knew I would end up liking him. SOOO we both do choir at my school (ikr its crazy how hes so cool and manages to sing too anyways enough ranting XD) and our choir does an original musical every year. This musical was based on a 50s American bandstand and it was called the rick stark show. So we had to learn how to swing dance and I was partnered up with who was soon to be my crush because we had to partner dance so much together and we had main roles that interacted A LOT. Anyways, skip ahead to the actual show, when I started to suspect he likes me. So one of his sort of friends comes up to me and asks me if I like my crush. I answered with why are you asking and he said "cause [my crush's name] maybe kinds sorta likes you and hes trying to ask you out at the cast party!" And my crushs other friend runs up to the kid I was talking to and said hes not gonna do it!! and the kid runs away. And my friend heard my crush talking about asking me out too. But I ended up telling the kid I liked my crush and he actually told my crush and then it became a littttlllee bit awkward (not a lot though). After the last performance, my mom wanted to take a picture of us and I naturally pt my arm on his waist, and he was hesitant at first but he ended up putting his arm around my waist too. At the cast party he never asked me out though :( but he did sign my shirt with a longer message than he wrote for anyone else. Later, I decided to dm hi on instagram cause I never got his number and I wanted to send him the picture. So I sent the picture and he said omg thanks so much I cant believe its over and I said ya its weird that were never gonna do it again XD <3. and he said ya but at least we ended on a good show <3 and I said ya but im gonna miss it (kissy face) and he said ya me too and I said but at least ill see you at the choir competitions and stuff still XD and he said ya I cant wait! and I said
