I tend to agree. Sometimes, doing nothing is just that. Nothing. I've read the carrot/stick theory. Tough love at its finest. Operation Snoop is underway. Stay tuned.
I received advice to not interfere at all in her affair, just to be loving and the nice guy through all this. I used to joke that they were stopping just short of telling me to hold her hair back for her while she blows OM. The Marine in me absolutely could not follow such a model. There is only so much sh!t any person will eat. We all have our limit. I ate sh!t for a year and a half and then said F this. In my own case that was when the worm turned. Will that work for others? Not necessarily. Even though so many of these things are textbook and most cheaters follow the same script, it doesn't mean they're the same people. Your cheating wife might be very different from my cheating wife. Nobody knows your wife like you do. Not even OM. He just knows the fake version of herself that she projects to him.
The reason your loving spouse is always the better choice is because they know the real you. They know all your faults and shortcoming and they still love you. If there is a person in your life that knows all your shortcomings and faults and still loves you then you should not throw that away.
Those aren't my words. Those are words she got from a good friend and she shared them with me later, after this sh!tstorm had subsided and she had rejoined the sane world.
