I am a few months behind you but I can completely feel your pain. I haven't had to "hand off" the kids yet, but I am bracing for it. It sounds like you are handling yourself with class in dealing with your H despite an extremely emotional situation. I wouldn't beat yourself up for not saying "exactly" the right thing. I would give yourself a pat on the back for coming as far as you have come!
