Who says she's didn't know or even if she cares?

> I was unfaithful to my wife. My actions hurt her and our children. There is no excuse for what I did. I am deeply sorry.

I don't understand what compels people to make up scenarios to defend people who have come out and said the opposite.

I think the "formal apology letter" wouldn't have existed if this was some sort of open-relationship situation. In that case, Huang violated an important agreement, and cannot be trusted to not violate other important agreements.

Well you could read the letter he wrote but why when you can just ask empty edgy questions to farm karma.
