I always considered that people who “recovered” from infidelity in marriage simply made an accommodation. They did not repair the relationship; they just chose to forget that the relationship was destroyed. For money, for convenience, for whatever reason. As they say, you can only lose your integrity once. I think that applies to marriage as well.
My husband of 27 years had an affair once that trust was gone the marriage was over!! I kicked his ass to the curb and never looked back!! I don’t know how some women can forgive the betrayal I guess I am not that strong!!
Integrity ho culture gone. Symptoms, disease, hypergamy, uncertainty, no peace, distrust, distress.
New creation: Signs. Shame-regret to Redemption, new life, Trust-Worthy, faith, hope, love, peace Forgiveness Corinthians 13
Forgiveness, greatness.
Something like 80% of couples don’t recover from infidelity. Of the remaining 20%, some are as you suggest. The rest do recover. It takes the person, who cheated, the understanding that they have to be willing to be held accountable forever until the mate has completed their grieving process. It means always keeping their location on, the willingness to be checked upon randomly. Answering all questions, no matter how salacious or damning.
The spouse that was cheated upon gets tongrieve their loss, no matter how long it takes.
