My only advice for the talk with the kids is make her tell them why. I also wouldn't try to make them excited about the situation. Tell them everything will be fine and you both love them and it is not their fault.

I didn't lie to them but I also did not point any fingers at W.

My w tried to get them excited about all new stuff and all that. Backfired on her. They don't like it there.
She spent so much money trying to buy them wanting to be there. Hasn't worked.
