Is it ever too soon to tell someone you like them?

If you know he likes you, then why not go ahead and let him know you like him, too? You can try casually touching him, or ask him to do something alone with you, if you are usually with other people.

Have fun! I don't see how it could be too soon here.

When you guys talk, make sure it's after like 2-3 weeks after he knows something about you and if he sees a connection or if you give him signs.
