In a sense I don't have a problem with the basic mechanics of the romance.
He can see the future (to some extent) he knows they will be together and it's been an obsession of his since he was a boy, he doesn't have the emotional maturity to cope with the fact she doesn't feel the same way yet (largely because the Jedi don't let him develop it) so he tries to force it to happen.
She has probably not given him much more than a nostalgic thought once in a while since they first met and suddenly there's this young man coming on really strong and it's making her understandably uncomfortable.
But why did they have to make it so bloody obvious?
Ric, did you write those scenes?
In this instance the incidental music seems to be telling a different story from the dialogue.
It's all romantic pastoral sweeps when the scenes themselves are edgy and uncomfortable (like teenage romance angst should be I guess but the miss-match is jarring in a bad way) though the actors themselves add to screw up by turning and edgy angsty scenerio into something rather embarrassing.
