I personally can't imagine trying to work through something like that without a couples councelour. I've gotten a coule Relate books on rebuilding trust in relationships and have found them incredibly useful on my own - Relate books aren't flakey worded or fully of California speak or have inspirational quotes in them, just very practical advice and homework.
