Do not under any circumstance sign any papers for him. If you are asking God to bring you two together again, then don't give in to the devil's desires. When you see or talk to your husband talk to him very kindly without any pressure. For it is God who will do the work in him not you or anyone else, remember that. Let the love of Christ show through you toward your husband, that will be more effecting than the pressure the other woman is putting on him.
Dear Lord I pray you take that other woman out of this man's heart and mind. May he return to you and his wife repented of his sins and ready to be the husband you want him to be. Have them become an example to others of the wonders you can do for us. Bind them together with your unconditional love and may they be joined this time with a real commitment to you and to each other full of love, forgiveness, understanding, kindness, respect and fidelity. Give Jessica the strength and wisdom she needs to wait on you. Heal all the pain and fill her with your peace and strength. Let her husband see she is a better woman, the kind any man can desire to have for a wife. Have him see the other woman as a nagger, controlling and selfish person ready to do anything to destroy marriages and take away what belongs to someone else. May he soon start to be disgusted with that other woman and find his wife a refreshing woman to be loved, admire and respected. In Jesus Name I ask you amen!
