she's his second chance. his chance to make up for what he didn't do before. another opportunity to be happy. another chance to get it right. she's not the same as what he had the first time. but thats what makes her unique. she gives him insight. she listens. she stays no matter what, and he knows that will never change. But most of all, though she'll never admit it to him, he knows she loves him. and that's what keeps him up at night.
