Baptist minister John Gibson's body was discovered by his minister wife Christi in their New Orleans home in August along with a suicide note which acknowledged his shame at being exposed.
The 56-year-old father of two also suffered from depression which he alluded to in the note he left his family.
Gibson ended his own life just six daysafter his name was one of the 32 million released during the cyber hack of the cheating website AshleyMadison.com.
"He talked about depression. He talked about having his name on there, and he said he was just very, very sorry," Christi Gibson told CNN.
"Nothing is worth the loss of a father and a husband and a friend. It just didn't merit it. It didn't merit it at all." she added in the company of her adult son and daughter.
"It wasn't so bad that we wouldn't have forgiven it, and so many people have said that to us, but for John, it carried such a shame."
"What we know about him is that he poured his life into other people, and he offered grace and mercy and forgiveness to everyone else, but somehow he couldn't extend that to himself."
Ashley Madison, launched in 2001, is known for its slogan: "Life is short. Have an affair." It helps connect people seeking to have extramarital relationships and is owned by Avid Life Media.
