Don't know if I can give advice on the boy situation, but I'm willing to try lol, so what's up?

Totally up to give advice! just let me know :)

It doesn't sound crazy at all!! I guess you could always contact him if you really wanna, text him just to see what's up, see if he wants to hang out sometime. That might be scary, but maybe he wants to see you too, you know? One of you has to take the first step. You could always wait till next schoolyear and see what happens, but regardless of your feelings, if you want to keep the friendship you'll have to actually do something about it

And if you have feelings for him, you can always see where it's going, but I think it's better to go back to being friends first

Feel like I'm not the best at this, but these are my thoughts :)
