Person B

Imagine person A.
Person A forms a relationship with person B, knowing that person B suffers from depression.
Person A thinks they can handle it.
Person A cannot handle it, and gets out, shortly before person B commits suicide.
Person A then uses the fact he had a relationship with person B to have sex with person C.
Person A leaving may or may not have been the trigger for B's suicide. I can't remember, and it doesn't matter; it's just a story.

But what if person B didn't die? What if person B is stronger than that?

What if person A wrote that story, shortly before they left, and then person B read it.

How much do you think person B would hurt?
