This is quite telling of why Joshuah blanched when told of the couples splitting up:

"Sharon and I have a specific strategy every single day; Sharon is everyone's best friend and Joshuah is in charge of putting everyone in their place. Sharon does the underground work and Joshuah verbally attacks."

Nice long-term strategy, there, arse.

And this really pi$$ed me off:

"I have wanted to break down so many times in this insane asylum...I will owe you big time when I come back from war...I will buy you all the buffalo wings and beer you want when I get out of this prison..."

One can pretty safely assume that Joshuah has not (yet) been mentally incompacitated to the point of institutionalization, or been in combat in a warzone, or been locked up in prison. So how dare he presume to know what any of these things feel like? All are life-altering and life-threatening experiences that are very painful for everyone involved. How dare he cheapen these experiences by comparing them to a friggin' reality TV show for which he is being compensated, fed, bathed, and pampered? How can he know about any of these things if he has never walked in those shoes?!

Just sayin.
