flipper,
I saw my brother go through a very similar thing. He was not invited to his only two daughter's weddings, and has never seen any of his grandchildren.
I thank God all the time that his spirit pulled us out before it got to that point, but we still did not come out unscathed.
God's spirit rescued you and it can rescue your daughter too; don't forget it.
Pray!! Because reason alone may not be able to penetrate the darkness that surrounds her!
"The light shines through the darkness, and the darkness can never extinguish it." - John 1:5
