Dear Erica,
I made a short prayer about this and by the grace of Jesus Christ, and the faith we have, your husband forthwith would not be unfaithful and the unclean spirits propelling this sort of behavior has permanently departed from him. I am new to this family, so I am unsure what kind of posts are allowed here, if you can, google for a church called "Mountain of fire and miracle ministries" and seek for a prayer partner there and together keep on praying for your husband with them, if your husband wants to be saved it would also be a good idea if he came with you to the aforementioned church.
