Most Helpful Guy
Yeah, I'd say go and tell him right now too. Do it like this:
1) Hey, do you remember telling me that u had a crush on me?
2) Yes, why?
1) I kinda have feelings for you too, I've liked you for (let's say 1 year) and I really want to tell you it, I hope you still have feelings for me...
If I was him I'd say yes to this
