I think you missed the point (or rather I read it differently). There WAS a resolution.
By her asking the question out loud to him, made this situation real (which she has probably practiced a million times in her head). At that very moment she self-realized the resolution she needed. He didn't have to answer because she found it herself. But only by him being there for her to ask the question was it possible.
She says she doesn't feel better, but the confrontation actually did and she can move on.
Well, do you think that if Duncan (the skater) thought about the question and got back to her with a yes or no answer, she wouldn't then feel worse?
I think that he is a different person now and the question is irrelevant that Phoebe very wisely figured out. The answer is useless, her realizing that is priceless.
