This is a really long story. Please answer only if you have time?

Well, i'm in a similar situation to you.. except im not involved in a choir. I like this boy who is a couple of years above me, we used to text all the time and talked alot.. he came round my house and we had a lovely time.. and he also came round the next day. But after that, he's completely stopped talking to me. He doesn't return my texts. I always feel obliged to look at his facebook profile to see what he's up too, and i get jelous when he talks to other girls. I don't know what to do either.. I guess you should ask him whether he had feelings for you, without telling him that you like him. Do it subtly like 'Do you remember how we used to hang round all the time..' and 'Did you enjoy it?' or 'Do you miss it?' it may work! and Good luck!
