bluestang, You, your daughter & your family are in our prayers. Your story sounds very familiar, we went through the same thing a few years ago. Fortunately after many late nights of talking she saw the light, dumped the guy and is now happily married to a guy that treats her like a princess.
I pray your story turns our as well as ours did. I know things looked very dark for us for a long time, and turned out O.K. Keep the faith and keep communications open at all cost. Sounds like you are doing things right. Keep doing what you can and put the rest in God's hands.
