Don, let me tell you that I think that you have done a fantastic job of trying to save your marriage. You have respected your wife's space, taken care of yourself, and have been spending valuable time with your children. You should be proud of yourself.
Remember that we can only change ourselves. We can't change our W's, only they can do that. I know every day seems like an eternity waiting for them to come back.
MW, you haven't done anything wrong. Obviously she is very confused and is having a hard time making rational decisions. I tell you that I see lots of signs of her not wanting to end your M. I really think these will continue to surface. Keep the faith and keep doing what you are doing.
