Wow! I feel so sorry for this man and his wife! All I can say it certainly doesn't sound as if she is using NFP properly and fully, and neither use it in the light God meant it to be used. It sounds as if they have deeper challenges and he is using NFP to blame. We have been married 16 years, some with contraception, some with no method and currently with NFP. I can't tell you what a wonderful difference it has made in our relationship...underneath it all we have learned what marriage really is meant to be in God's eyes! I wish we had the blessing of learning this when we were first married! I hope you are able to open their eyes to the truth and point them in the right direction for the wonderful marriage they can have. God Bless you for all you do to spread the truth
