No no no! Yuck. I wouldn't have read it if it was.
More like buffy who still thinks she and angel have a perfect true love has more of an opportunity to realise that it isn't all that different to any other relationship when she has the experience of him sticking around and sees him through a more grown up perspective. Assuming I didn't imagine the whole thing anyway
and on the same assumption, I'm starting to feel pretty sure that spike turns up outside the Bronze as normal but she can't bring herself to stake him because she has a flashback to after glory beats him up. I'm not 100% sure that bit isn't mixed in from another fic either though. The only bits I'm certain of are ressurection spell and Buffy from Bargaining with attached baggage turns up when Xander does CPR.
