Clay234 - thank you for your post. Sounds like my estranged wife. She has also left me numerous times to live with her parents. Right now, she has managed to get them to move from their home country and move in with her in a one-bedroom tiny condo with our daughter, and the parents are sleeping in the living room.
My wife also was not loved in the family and was considered last, living in the shadow of her older sister that got all the love and attention.
I've lost hope that my wife will ever come back. I'e lost her and my much adored daughter.
