Lord have this man see that what he is doing is not what a grown up man does. May he see that his mother is still tying him to her umbilical cord and not allowing him to be a man. This is an unhealthy relationship he has with his mother Lord. Give his wife comfort, strength, and wisdom at this time to see her through it all.
Have this man's mother get out of their way, and allow them to be on their own to form their own family without her interference. Bring this couple back together again and restore their love for each other stronger than before. May they allow you to guide their steps from now on so they can have a more fulfilling life and marriage, I pray in Jesus name.
