Hey LonelyD - I've been reading your thread - and lurking for a while - and feel for you. My W just moved out at the beginning of this month - and I'm still in the early stages of dealing with the loneliness and the pain - and the rediscovering of my personal strength. You sound like a good, strong man - and I think it's great that you're staying as steady as you can for your children - be proud of that.
You've been getting amazing advice from AmyC - and I think Dday was spot on - drop the expectations from your W - just focus on you and your kids - embrace that calm that you've found in the home.
