What does it mean when a guy thinks highly of a girl?

Sounds like he has great respect for you. Could mean much more, but who knows.

Why not Ask him to explain further. A month ago you asked a similar question and the answers are still the same.

He's standing on a ladder.

Seriously, it means he is a nice guy and doesn't want to hurt your feelings, but he is not interested in you as anything more than a friend.

There are plenty of other guys in the world. Give up on him and find one who cares about you as you care about him. He's out there.

depending. Maybe you are one of the few females he can truly say that too/about.
