I do understand what you are saying although my D is not final yet, it will be in a couple of weeks. I am not ready to give either. I just read a post by David A entitled something about the big picture. His wife had married the OM and is leaving him and coming home because she has come out of her MLC.
I don't think that the people posting here were trying to put you down. I think that they are trying to save you the pain of waiting for something that may never happen. It would be a shame for you to put your life on hold and not get anything from it.
I am not Catholic but I too, believe H and I are still married in the eyes of the Lord. Try not to take the advice personally. My suggestion would be to put on your best smile and show your XH just what he gave up. That is not pursuing him in any way.
Everything happens for a reason, maybe Dad needs to find that it isn't better out there, he needs to realize how good he had it here. Maybe he will find God and that is the most important thing when he finds Him he will know he is supposed to come home.
