I think about my crush whenever I go out
Isn't that cute? Are you going to confess?
I do not know the answer.
It is normal to think about the person you like. People do that all the time but you will be able to think of other things if you let them know you like them and see where it goes.
I don't think they will ever know.
That's really wonderful you've found someone and can think of them nicely, but don't you want to know if it's something to pursue, or if they'd like you back? You'd never know if you try!
