I think it is possible that spending so much time around o.w.'s daughter, coupled with her telling him that she was pregnant at one point may have stirred up feelings in him that he had not felt before. He has said to me on more than one occasion: "When she (child) sees me, she runs up to me, tells me she loves me and gives me a hug. When someone does that it makes you feel really good." I am sure that it does, but when our little niece would act that way with him, he didn't seem to respond to her the way he has with o.w.'s child. He has told me he wants his own children. I would love that, too, but right now I'm not even thinking about adding a child to this mess; that would have to come down the road.
Most of us really marry only once. First love endures, even unto our dying day. And we never really divorce.
