D8 has said stuff that completely isn't true, and I do believe some of it because of the conflicting morals she is getting
Jon, it is too long of a story to get into, but I use to have a step-granddaughter that there was the same situation and it was awful what it did to her. Her mother left her when she was a baby and the dad raised her and had full custody of her, but she went to her biological mother's every other weekend. Her mother had no morals at all. My daughter M the little girl's daddy and we took her and loved her as our own. They tried very hard to raise her right. Ten years later my D and SIL divorced. I saw the girl one time after that. The last I heard it was not good what had happen to her b/c of the influence her mother had on her. But during those ten years, every time she would come back home from being with her mother, it was as if my D and SIL would have to start all over and try to get all that garbage out of her mind and instill the right morals. So, I guess that is one reason I was so emotional about your stitch and I hope I wasn't sounding too over-bearing. I shared this personal experience to just let you know that I realize some of the hell on earth that it can put a parent through, plus the grandparent that love her and want to see her grow up to be a good person.
You have my prayers. I hope you can find out the truth and if your W is having a PA, you can move on and get a life. There will always be that connection b/c of the kids and that is so difficult even under the best of circumstances. But, I pray you will find peace and that God will give you guidance as to what to do.
Take care, Sandi
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
