BBM: The children have went through so much already, I do not think they need a "made over" dad at this point. Sorry if this has been mentioned, I am catching up on the threads.
BTW: I feel the same way about the kiddos returning to the house. It is likely the only house they remember living in, having dinner in, birthday parties, holidays, Christmas mornings. She was just such a strong force, in my imagination, they can even feel her presence. They can be around their dogs and toys, they could wrap up in her housecoat, her favorite blanket and just be around her...
