I personally know marriages that have survived adultery, alcoholism, domestic violence, and polar opposite personalities. I also know a marriage that was reconciled after an 11-year divorce when the parties didn’t even know where each other lived. (See their story at Inverse Ministries.) I have read about or watched videos about marriages that have survived mutual restraining orders, homosexuality, etc. But with God, healing and restoration of relationships is possible.
I just watched a movie last night about Lori Wilson, the wife of Bill Wilson who founded Alcoholics Anonymous. It was an amazing story of a couple hanging in there through some awful circumstances and still eventually thriving in their marriage.
