You should tell him
you should ask a friend to tell the guy that you like him or you should go up to him and tell that you like him.(because i did that with my crush)
Yes
If you don't tell him, he has no chance to respond. But, nobody here knows you or him, so it has to be your decision.
You should do that.
No expressing yourself is not weird. If you are in love You should tell him.
Tell him that you really like him.
You should tell him how you feel. Best Wishes!
