Hi. [An awkward pause, and then it's all a bit of a rush.] I'm sorry. I can't...I can't do this anymore. It's not fair to her. I know it isn't, and I did it anyway, and she's probably going to hate me for it later, but we both know another ten years isn't going to change anything. [A pause as he takes a deep breath, but then, just because he needs to make sure, there's some hope in his tone. Hope for which answer, he's not sure.] Right?
