Welcome to divorcebusting.com! You have been given some GREAT advice by mmf and Tipper. They are wonderful DBers.
Retrouvaille is a marriage saver for many, and it seals the deal for divorce for some...especially if they were thinking this was their last shot. It isn't, it's just a tool, and can be a great tool.
Some of those ebooks give very bad advice mixed in with good advice, so you think it's ok.
Divorce Remedy is DivorceBusting upgrade, with chapters on Infidelity and MLC. The MLC chapter is here on this forum (at the top).
The MLC community on this forum is probably the most supportive on the board. It's a very loving group and some of these folks have been DBing for quite awhile now. That said...while you stay here for support, I don't want you to ASSUME your life is an MLCer even though you see all the signs and someone here may tell you it's just like their wife, etc. Thinking she may have an MLC is best used to help you understand your wife MAY be going through, but it won't help you find a lot of solutions.
So, in that light, I'd like to see you start with some solution detecting.
Besides telling us a bit about your family, also tell us what your wife's complaints have been about you/your marriage, and what you were doing when things were good.
Hang in there, we'll support you, pray for you, and help brainstorm solutions. sg
