Being warm, friendly and neighbor-like is for people who are trying to make positive changes in their own lives and perspective, yes, but it's also to re-attract their spouses and get their Ms back on track. I'm not saying you should resort to being nasty, but why WOULDN'T you be distant toward your H right now?
It's gonna be hard to continue saying "get out of the house and my life, you freaking selfish turd" in a warm way, with a smile on your face, right?
So what is your ultimate goal? Still to get him to leave?
