Not enough info.......but on the face of it the husband turned the child back and the wife now needs therapy? Weird.
I knew a family that had adopted a baby girl and then the mother almost immediately got pregnant and had a daughter who therefore was less than a year younger than the adopted child.
The entire family immediately forgot about the adopted child, and to make matters worse, the little girl was a sort of podgy, dull-looking and timid creature who was a real klutz and did everything badly (possibly because of constant criticism). The natural child, her younger sister, on the other hand, was tall, slender, blonde, a born athlete (like her mother) and did everything well. Needless to say, things were horrible for the poor little adopted girl.
When she was about 9, she was molested in a school situation by an older man who hung around women with access to children (teachers, etc.), since she was a classic victim - insecure, rejected by her parents, etc. But her mother wouldn’t even press charges.
Maybe this child is lucky that they “sent her back.” I doubt that her life was particularly pleaseant before that, but she was probably fairly well brought up, and perhaps some good Christian family will adopt her.
As for the husband and wife and their dynamic, who cares? I think they’re both tripping down the broad and easy path...
Not enough info? They had this child for seven years and then decided no thanks? What do you want to see, that she ran with scissors?
