How the fuck did she destroy it if all she said was "well, nobody can know for sure what the future holds, but they love each other very much". And that is true anything could happen, but more in the sense that, Earthni is a wild fucking place. Weird shit WILL happen.
That being said, after being wrangled around for so much but still wanting to be together, I think pretty much nothing will separate them. They can't be separated.
