Friends?

Hello. I just want to get this out of me cause it’s kind of pulling me down. There is this one boy I knew he exists and we talked together ones at a jazz concert. Afterwards I thought we were gonna become good friends but nothing of what I pictured happened and I guess that’s fine. Alright I got over it but now after 6 months we talked together and spend the whole day together and with others too because it was arranged by our piano teacher. It wasn’t just us there other people were there too but we mostly hang out and really got to know each other “more”. It was really nice to talk to someone who is around my age. I felt like I wanted to get to know him better and would like to be friend with him but I don’t want to push too much on that. I would really like to have some friend but don’t want to rely on that. I perhaps don’t want to give myself false hopes. I don’t know. What if he get scared or I don’t know didn’t want to be friend with me. I just don’t know. I know that I know nothing. We had a good time and we laughed together and talked kinda lot and I was enjoying it. I wish I could do that again or take the time back to talk with him and be around him.
