well, here's my 3cents from my own personal struggles.
I agree on the house / home thing. I understand where you're coming from in that sense. It too was hard for me to get adjusted to a new "home" so far away from my family. It's extremely difficult to leave your home. One day you'll build a new and better home, your W may or may not be there.
W is selfish, she will only think about herself for the next idk how many LONG months to come. the sooner we get used to it / accept it the better for us.
try not to worry about what your W will or will not do after the affair goes up in flames. It's no use. And not to give you false hopes or anything but, my W is very stubborn and prideful, never apologizes for ANYTHING or cries, and she's already half apologized for some stuff and cried with some regret. Your W already surprised you with an affair, therefore you may be pleasantly surprised in a different manner. one thing i've learned, ANYTHING is possible in this journey.'
glad you're moving out, in some sense because it'll be good to be out of the immediate stressful situation. It will certainly help you take care of you and worry only about you.
