This is a new viewpoint and I think it could be right on. Rachel did change as the show went on. I've often asked myself how I could have so liked her at the start and so despised her by the end. I do think Peter really loved her, though. His hesitation over a proposal could well have been his uncertainty over who Rachel truly was as the season progressed. He never led her on and was always truthful with her about where he stood, but her ego couldn't accept that. I, too, think she's still pissed off, and it's pretty remarkable after all this time. It must have occurred to her at some point after the show that, if Peter really was the jerk she keeps describing, he would have easily played along and then just broken off the engagement. And if it truly was, as she says, "always Bryan," what's still to be so bitter about?
