My wife just moved out. It wasn't pleasant to see so much of our lives heading out the door, but if it happens, it is survivable and you will get through it.
I think my wife is already beginning to realize that the dream wasn't what she expected. I know that she woke up crying last night. She's already easier to talk to; she doesn't parse every word out of my mouth. I don't know what the long term effects will be, but I'm hopeful that it will turn into a positive step forward.
