Mary,
 
I will be praying.  It is a very hard thing to go through.  I pray that your daughter-in-law will repent and come to terms and not remain in denial for her deeds.  It can happen as my father did with me and wept for his sins.  We now have a good relationship and talk about the Lord often.  I pray for him to come to faith in Christ and I will be praying for your family.
