Hey RT, you said exactly the right things but continue to be careful with the boys. A year from now you'll see the fruit of that behavior. More so in following years. Believe me, it pays off in spades...
As for the emotions. Has it ocurred to you that you have been repressing many feelings? I think that helps the feeling of being hit by a brick, even though you knew it was coming. The changes tend to cause you to feel new feelings and that brings up the past feelings you didn't finish with. There will be more.
But I think you have a good handle on it. You didn't want it, but you're not stopping it either. You're choosing to act with dignity and grace and to cope. You'll find that that approach will pay dividends later, although it means you'll be dealing with it longer. There really is no other good way to deal with it. Face it head on and deal with it as it happens. Don't leave feelings for later if you can help it.
Keep strong for your kids sake and yours. Your perspective and attitude will see you through better than you may be able to see right now, but it will pass and life will be much better out of limbo land. Seriously.
