That vow leaves no room for infidelity. Be honest with each other about personal needs and marital problems. While sexual addiction, personality disorders or a search for validation can precipitate an affair, most affairs reflect problems in the marriage. The best way to beat temptation is to prevent it from coming. Make sure you're connecting with each other and that appropriate needs are being satisfied at home.
Honest discussion shows a commitment to both spouse and marriage.
You're willing to take a chance so you and your spouse can address what's important to your marriage's vitality. Talk frequently and openly with your spouse. Allow your spouse to be open with you. It's easy to express your unmet needs but far more difficult to hear about your faults. Don't allow jobs, hobbies, parents, school, church or kids to crowd out the attention that belongs to the marital bond.
