JR, I've done similar things, though not for as many nights. And although there was initial disappointment, and even worrying about what my W would do -- i.e., go out and cheat -- eventually I settled onto the feeling that it's a necessary and good thing for my W to be alone. She needs that time alone to feel what it's like to be alone, and to sort out her own feelings.
In-house separation is classic Greek tragedy: everything is set up to fail.
I know it scuks, but just trying to put a positive spin on things....
