Ending Question

Here's what happened as I saw and understand it. It's pretty lengthy, but it sums up the last 15 minutes or so:

When they went out to the restaurant she wanted to go to, and Michael talked to the maitre'd about going to college with his wife, the maitre'd asked if he was a writer as well. He replied, "No, I'm just a cabbie".

That's when Sarah suddenly had her mood change. She remembered Michael told her he was a writer, but here he is saying publicly he isn't. Sarah thought that he had lied to her and was just playing her all along.

The argument in the cab ride home, and the subsequent dialogue in the home explored this. She said that Michael couldn't know what her life was like, and we then find out that he had written a best selling novel years before and gotten both rich and famous because of it. Michael said that all that wealth and fame thrust him into a world he soon grew to loathe because of what it was doing to him. This world was her world, and he saw that it was starting to do the same to her.

Sarah however, still didn't believe him regarding having written the novel. Nevertheless, they spend one last night together (unbeknownst to Michael) and she returns to Paris to be with Phillipe.

Michael rushes to Paris, finds her, and that's where she sees him and essentially tells him to keep quiet about everything. Michael, meanwhile, has a decision to make about what to do next. Does he let her go, or does he tell her one last time about himself, and everything, even showing her?

Later in the movie, when Sarah is in bed with Phillipe, the bellhop delivers a package for Sarah. She opens it and discovers both a letter from Michael, and lo and behold, that novel that Michael said he wrote years before, and that Sarah didn't believe he had written.

Michael confesses his undying love for her, and says that if she leaves her world and comes to his, it should be for herself, and not anyone else. He states that he envisions the two of them just walking in the park, or taking a stroll on the beach, like a normal couple in love.

That's when get the eventual ending where the blurred visages of Michael and Sarah are strolling through a park. However, they are off in the distance, which to me means that it doesn't happen right now, but sometime in the future. You can make out Sarah's blonde hair as they get closer though.
