Aww, big hugs!
I think you've already taken the biggest step -- you've apologized. I guess keep on doing that until they no longer feel it's necessary.

A month ago today, I was verbally attacked by someone I love. I'm still devastated. She has not made any attempt to apologize. So, I can only assume that she believes the awful things she said to me. Unfortunately, that will be the end of this very important relationship.

So, keep apologizing. It will make a world a difference.
