If you have the Divorce Remedy by MWD her chapter on healing from infidelity should prove helpful. Her advice to the unfaithful spouse is important.
When my wife supposedly broke off her affair with OM1, someone once said to me, make sure you don't crawl on your knees through glass -- that's her job. There was a brief honeymoon period (2 weeks), but in the end, she didn't ask for my forgiveness for the affair or think it was wrong AND she refused to divulge any details about it. In addition, she didn't want to go to Marriage Counseling. In most affair recovery material, complete transparency about the affair is necessary. Why? Because betrayed people feel like the weeks and months during and affair, their personal history was robbed and stolen -- their life was a lie and they need the facts to make sense of their own journey.
