I feel bad I broke his heart?

Years ago a rejected a guy, told him its because he is a year younger than me. I never even gave him a chance.

We remained just friends. He told me today that he is in a relationship now. And he also told me exactly how much I hurt him and how much I meant to him.

I never realized how much I hurt him and I told him I was sorry. I feel horrible about it. I know I don't deserve any sympathy. But what would you do? How would you handle this situation?
