I'm happy to hear that your husband has come to his senses. He is right, he has made a terrible mess, probably more than he imagines, or wants to face. One book that my H and I read when we were reconciling, that we found helpful was "After the Affair" by Janis Spring. Also, I don't know if you have heard of Retrouvaille, but they offer weekends where couples are helped to reconcile. The Retrouvaille program is particularly effective at helping people to recognize their mistakes and get over the past, allowing the marriage to move into a much better future. A list of locations and weekends can be found on their website, www.helpourmarriage.org.
