It is useful to understand that cheating is a symptom, not a cause.
The appropriate question then becomes,
1. What is, or are the underlying sources for this symptom, this chosen behavior?
2. Is there sufficient love, relatedness, and desire present to even engage with the first question?

Couples have begun to restore forgiveness and re-reestablishing trust when they avoid. playing Wack-a-Mole with the symptoms and have begun to address the sources of infidelity.
Disappearing an “iceberg of symptoms,” new possibility for a vibrant healthy marriage arises. One pathway forward together is to read Gary Chapman’s “The Five Love Languages” Reading aloud together (WE-educationally) We become aware that each of us feels loved in slightly different ways. He distinguishes five love languages: Quality time, Acts of Service, Words of Affirmation, Physical Touch and Receiving Gifts.
When you love them in the love language that works best for you it is, inevitably, not the love language they most need to hear from you. It has happened that, after a while, they begin seeking out what they require to experience love from someone outside the marriage covenant. Infidelity arises.
When couples learn their love languages and speak to them with one another marriages can be restored to health.
