He sees you as his precious friend and nothing more. But you've both developed a codependency.

You weren't there for each other when you both needed each other the most.

He's childhood friends with you since birth. Both of your families are close as well.

He attends college with you.

He's protective of you.

His dream of being a tennis player was torn away when his wrist was broken.

He doesn't like you romantically.

He doesn't flirt.

Neither of you have hurt each other.
