So Buffy figured out that they just kept her busy, making her work.
It took me years to determine what love was. It's when you don't know where you begin and the other ends. It's where you close your eyes and still feel them near. It's not about fear to be alone or being used to them being around. Hell it's not even about thinking about them all the time. It's about knowing when you're complete and knowing who brings the best out of you.
Did Angel understand that? It was very clear :)

Author's Response: I think Angel might still be in denial a tad. I think he's used to her world being about their unfinished love affair but really he has moved on as she had. I really would have thought he would have a hint as to the fact that they just aren't romantically in love with each other anymore. Perhaps Angel just hadn't gotten to that point yet.
