saran on a crush?

Being male and having some experience with this sort of thing, I think anda should go somewhere private and talk to him a bit, and ask when it seems the least awkward. If he likes anda then he will either tell anda so almost immediately when anda ask, atau act very shy and embarrassed, and try to avoid answering. If he doesn't like anda (romantically; anda can be friends either way), then he will say so, atau he will think going somewhere private is odd and misleading. The worst that could happen is he will say he doesn't romantically like you. Discovering that early will be far better than trying to find out for far too long, rather than consider someone who might like anda back. It may seem embarrassing atau make anda nervous, but relationships cannot exist without a beginning. The best of luck!

just ask him if he likes anda I did that and needless to say a tahun later we got married. if he doesn't we'll his loss

Worst that could happen is if he say no.
Worst that will happen if anda never ask is a bunch of nervous tension of "What if?".
You'll either forget about him atau regret never asking.
So go ask him out.

Talk to him

I know this has already been berkata oleh everybody else & can be easier berkata than done, but talk to him. Chances are though, that he'll either say no atau deny it, but if he shows any of the signs (e.g. blushing, akting awkward, getting defensive) then he most definitely likes anda & anda should do something; atau if your to shy, ask 1 of your closest friends to talk to his best friend in case he told them. Just try not to get too depressed if he honestly doesn't, there's still friendship.
