This probably should have been posted in the JFO forum. In reality you just found out and this affair just happened yesterday in your mind.
Now take some time for yourself. You finally have the truth you have been asking for, looking for and really in your gut knew, that is a good thing. Many here believe it is impossible to R without the truth. It is truly shameful that she has lied for all these years making you feel crazy, but it is par for the course. I am glad the rugsweeping has started to end, if real R was ever going to happen it had to start with the truth.
I don't see any posts on how your marriage has been or how she acted when she came clean. Does she want to save the marriage. Is she different now than five years ago. Does she feel your pain (remorse)?
Please take some time to make this life changing decision.
DearPeggy com is full of resources for you as is the healing library here on SI.
Your wife must read- "How to Help heal your Spouse after an Affair". The book is short and to the point.
You might want to read a book on how to build a better marriage after this heartbreak. (I know the pain)
"The Monogamy Myth" by Peggy Vaughan she was one of the foremost researchers on infidelity.
I don't know your whole story but do hope the very best for you and your family in what may be the worst time in your entire life.
EDIT I just found all your posts in the archives, wow you have been in trauma for years. I also have a serial cheating WW and terminal cancer. I see you are a man of great faith with posts talking about God and your desire to be far from her. For me as much pain my WW has caused me and the daily trauma I relive. I still desire to see her as my wife in paradise. That is how I am currently trying R. I know God will relieve my pain in a few years and I hope to be with my WW cleaned up and beautiful when she arrives.
May you find the Happiness you Deserve.
