It's a story...all 3 of the girls thought the man their mother was married to was their biological father. Then mother and "father" just ran out on them one day. My W was 17. All 3 had to go live with their grandparents. It was not until 12 years ago that they found out each one had a different father. The whole family had kept it a secret from them.
So now one sister won't talk to the other sister and none of them talk to their mother.
My W found her real father 7 years ago. At first she kept close contact with him. The last several years, nothing.
It explains a lot of my W's behaviors. Her family is the poster family for "dysfunctional".
