Crush Dilemma

Angela
So I like a guy who is in one of my bands outside of school and it's only once a week. I've been in several other honor bands together without realizing. Problem is: A) we don't go to the same school, B) we never had a legit convo together, and C) we are not in the same group for that band outside of school so I only see him if I walk down to the rehearsal space to say hi to my other friends. We follow either on different social medias so we are aware of each other's existence. I don't know what I should do. Should I message him on FB? Get one of my friends to talk me up to him? The thing is, if we don't get along well enough to date, I'd still want to be friends. 
Please help me 😅. Xoxo
