The entire "meting Angel halfway between LA and Sunnydale" was another of those "left ambiguous" things that Joss loves to toss in every now and then. She came back and wouldn't talk about what happened. and on his own show, Angel did the same thing. Some people like to believe that they 1) renewed their declarations of undying love, some believe that, 2) upon meeting, they both realized that they had moved on to more mature relationships with other partners. Number 1, number 2, or something in between. Make up your own mind.
