Grasshopper asked me to stop in and read your story. I was actually the WAW (had MLC) in my sitch. I put my family through about 3 years of hell before I snapped out of the fog.
I'm standing for my marriage today, trying to reconcile with my husband and I definitely am standing on God's Word and His Strength to pull me and my family the rest of the way out of this pit.
You have managed to escape a good chunk of madness and turmoil. That's a miracle in itself!
Where is this person your wife had the A with? Are you still attending the same church? Were other church people aware of the affair?
For now, I'd say to read "Divorce Remedy". I just recently ordered another book called "Torn Asunder". It hasn't arrived yet so I can't recommend it one way or the other. Look it up and see what you think. My feeling is that it's going to be a good, informative read.
I'm usually here most of the time but this afternoon I will be out of touch for a while.
I'll check back in on you later this evening, though.
You're really in a better position than most of us.
