I quote Huiwen:

" "Knowing can be a curse on a person's life. I'd traded in a pack of lies for a pack of truth, and I didn't know which one was heavier. Which one took the most strength to carry around? It was a ridiculous question, though, because once you know the truth, you can't ever go back and pick up your suitcase of lies. Heavier or not, the truth is yours now." "

And yeah, sometimes you leave because you really want to stay.
Just like how you hate because you really want to love, no?

"You can't save the damsel if she loves her distress."
