Confrontation

Today, I am struggling with how to confront someone about their marriage. This marriage is heading down a road of a partnership for the sake of the children or divorce. How do you approach someone who has made life horrible for their wife and children? He has tried to control their every move, to the point of them not wanting to leave the house for fear he will get mad at them. Most everything is mental abuse and not physical. Thank our Good Lord for that. If you are a praying Christian person, please pray for this family!
