1. Build the marriage relationship - Communication is the key here. Staying in touch with each other's feelings, pressures and tensions will keep you focused on where your relationship needs work. Caring enough to meet these mutual needs in your marriage will help make your relationship a meaningful one in which to be involved. This kind of communication takes time. Make time for each other.
2. The affair process. Read thru again the 12-step affair process. Then read it with your spouse. Come to mutual agreements about how to relate to the opposite sex. The most important idea to remember is that all sin starts in the mind. If we control it there, it cannot grow. Turn your sexual fantasies toward your marriage. Control your thoughts. Pray for good dreams. God will help you manage this sexual dimension in your life.
3. Walk with God together. Be regular in fellowship with Christians. Be regular in worship. Be regular in your devotional life. Pray together as a couple. Go to meetings for men at your church. Men need to have a place where they can discuss openly and honestly with other men about the tensions and problems they encounter in life. Find a place of ministry in your church. Talk to your pastor, let him know your weaknesses and have him pray for you.
4. Count the cost. It helps us to keep our heads in the real world if we think about the consequences of infidelity. Think about how quickly your credibility and Christian witness would be compromised. Don't think temptation will never happen to you. No one is immune. Think about the fact that sin grieves our Lord. Think about how much it would hurt your wife, kids, parents, and in-laws. Even though thinking of the consequences of our sin can help us resist temptation, we are only truly moral in a biblical sense when we refuse to sin primarily out of our love for God.
Our goal in developing moral character is to get to the place where we act faithfully and consistently simply because to do otherwise would bring harm to the person and cause of the God we love.
Only a real and lasting love for God will guard and buttress our fight against the enemy.
