Pray and encourage your spouse to build a personal relationship with God and fall deeply in love with His word. Work towards becoming Christlike also to set an example.
This is necessary because it is only a spouse with a God fearing heart filled with the word of God and living an active committed relationship with God (not just a church goer) that can steadfastly stay away from adultery. Be married for life.
