Ending Explained (My Theory)

I know so many people who are upset with the ending because they take it literally, when it should be taken metaphorically and then it wouldn’t be so horrible.

I think that even though she looks the same, all the comments on the FL being old and such are trying to clue the viewers into the fact that she’s finished with her life. We already saw the flashback scenes suggesting reincarnation. This story has been told before, basically.

I think that she dies at the end, and then is reunited with him in heaven.
