My advice is to tell him if you don't want to regret it.It would be better to tell him and be shot down then to not tell him and regret it. But that's just my way of doing things.
My expriences?I have had more expiriences than you could imagine. Sure I look 12, I'm not a slut I'll tell you that. I'm 408 years old, that's a LOT of crushes. And I get that a lot. But if your shot down, hey, it wasn't worht liking him id he won't like you back, right? Right. So, don't worry if you do, because if you guys did get in a relationship, he obviously wouldn't be all gung ho about it if he treats you like that. So I say go ahead and try!
Go for it. I was in love with this kid im in band with, thought i had no chance, and guess what? Been together since october 2ndd. Theres no telling what could happen, just go for it!
I think you should definately tell him.
Other wise you'll have to live with knowing what if you said?
And what if he did like you and you didnt know?
You should tell him no matter what.
Because at least you know you took the chance to find out what would have happened.
Being honest about how you feel about people is a must.
Hope this helped a bit.
