Ok, in a perfect world Buffy and Angel would end up together, Angel all cured and human like, then they would live happily ever after.
But Joss's world has never been perfect, and like when Willow told Oz that part of her would always wait for him, I think Buffy and Angel, while surely a true love, may not end up together.
I love Buffy and Angel, it's epic, but nothing that good or perfect lasts.
if Angel is ever made human, and if Buffy and Angel do end up together, one of them will have to die, or both of them, or something to that extent. As much as I think Buffy deserves a "˜happily ever after' I just don't think she will get one with Angel, or at least not a long term one. not that they couldn't under the right circumstances, just that they have both grown so much as separate characters, and had many "˜loves' and losses since, that they never could relive their relationship. it would never be as intense, it would never be the same. I don't think they will ever get over each other, but I do think they have moved on. the drama and the pain is what made it so engulfing, how could they ever settle for anything short of going out with a bang? And sorry folks, happily ever after is not a bang. I could see in the end, Angel and Buffy coming together, but before walking off into the sunset, them looking into each others eyes, and both realizing it was over. Of course there will always be something between them, but I think the Buffy/Angel love relationship is something that can't be revisited, besides, it's epic, how can you top epic?? And since when do epic lovers get a happily ever after?
