I wish I could offer more, but all I can say is that I know what you are going through. My situation is very similar to yours. EA turns to PA, she moves out and here we are. Every day is a struggle. I also am the type to not talk to others about it, my wife was about the only person I really talked to about important things.
Hang in there.
