a sister gone off the deep end

[MarcieM]

So please explain why a scenario such as this does not violate the prime directive of not lying to your SO.
I purposely put in the word scenario because I am not necessarily talking about this one incident.

This particular case, if it's true (and the jury is still out on that) it violates EVERY rule of trust in the universe.
I'm sorry...but I have zero empathy for the person who went to Taiwan.
