If your husband is the way you described him, then he is committing adultery according to the holy word and you have grounds for divorce. God may not have intended this man for your husband, but you jump the gun and picked him for your husband, not God. God is good and he gives us blessings and answer our prayers when we are patient and wait on Him.
Lord show this woman she is wasting her time and youth with this man. Help her to get away from him as soon as possible. Help her not to fall herself into temptation, for if we stay with people like her husband sooner or later we may fall into darkness ourselves. Give her the courage, strength, and wisdom to start a new life again with your help, for you want us to be happy and loved. Teach her the next time to be careful with what kind of man she falls in love, may she have learned her lesson with this man. I pray in the mighty name of Jesus, amen.
