Dear Younger me,
Just because a man is good, kind, handsome, Godly, etc., and you are also a pretty darn good catch, doesn’t mean you’ll end up together.
If he doesn’t like you, that doesn’t mean you are less. Your identity, your awesomeness is not tied to him.
God loves you and if a good guy like that is not your possible partner, then trust that the Lord has something even better up His sleeve. Don’t start questioning the person you are. Start identifying the ways God has made you and blessed you.
