Oh yes I do remember that now @Faith-and-Hope and that is just such an awful thing to do. Including her in his dates with the new women! what is wrong with him. She is very vulnerable and that is so manipulative and disgusting that the new women is comfortable with that. 

He doesn't have her best interests at heart, and he is simply wanting to get you where he knows it hurts most. Or even worse wanting to rid himself of any responsibility around your daughters care.

This is a very stressful time for you. I doubt you'll be getting much sleep or a sound sleep for some months yet. All you can do is weather the storm.

Your head must be spinning at a million miles an hour. This man is a complete stranger. Really makes me wonder of the extent to his double life and how many years he has had this in the works, plotting, or living a double life on the other side of the world while you were at home raising the kids. 

At the risk of sounding too up front, I am glad your marriage is over @Faith-and-Hope . This is not the saddest and worst result, given who he is. How people treat children, the disabled and animals is very telling of their true nature and their character. It would have been so much worse if he had dragged you through this for another 10/20/30 years. 

I hope that your other adult children and family are supporting you as much as they can through this awfully stressful time. It will feel like a dream and a tornado all at once, you will have to pinch yourself in a few years time to convince your nervous system its actually over. 

Big bear hugs, Corny
