This situation could be about any non-Catholic -- a secular Jєω, an athiest, a congregationalist, a methodist, etc. My point is that the Novus Ordo brand of the Catholic Faith isn't helping this lady or her children much. It sounds like a huge mess!
There are some problems that anyone could experience -- and then there are problems that a good, devout Catholic family should never have to experience.
Please continune to keep my daughter and her family in your prayers. She needs to feel God's mercy for all of them, especially her children with high psychological needs. Also keep the children's therapists surrounded as they help them understand that Daddy's can do something wrong and he still loves them as they love him. Pray that she can sell her house before foreclosure and find appropriate affordable housing for herself and her children. Also that her husband be forgiven.
