We may not agree with the decisions of our children or grandchildren but unless you want to risk alienating family (perhaps) forever, I would bite my tongue & like the others have said, tell her you love her no matter what & offer any & all help that she may need. I may even take the initiative & call her FIRST !! Only God is perfect & there is no one on the face of this earth that can match that. Think long & pray for patience in making this difficult decision.
