This brings up a very salient point.
Christine's book is not called, "How to Get Your Midlife Wife Back" -- it's called:
'HOW TO SURVIVE YOUR WIFE'S MIDLIFE CRISIS'
There's a reason for that.
While it only takes one person to destroy a marriage, it takes TWO to keep it together/put it back together.
Every newbie comes looking on here for advice on how to SAVE their marriage.
If there is an OM (even if it's just an EA), the answer is that you must first DESTROY the existing marriage.
But to Faithful's point, the SHOCK & AWE tactics work better EARLY ON in the process than later on.
Let me go back to my cancer analogy (now famously preserved in Pexio's "Bystander's Words of Wisdom" thread

)
Cancer is most curable when it's caught in its earliest stages.
By the time you get to stage 3 or 4 with many cancers, the survival rates are very, very low.
That's why EARLY DETECTION is the key.
But more important than early detection is EARLY INTERVENTION.
It's not enough for an oncologist to see an abnormal polyp in the colon and say, "Hmm. That looks suspicious."
No ... they dive in deeper. They do a colonoscopy. Then they usually go in and remove it. And then they biopsy it.
Guys: If you're getting a warning signal from your Wives (ILYBINILWY, missing rings, secrecy with the cell phone, "you deserve someone better"), THE CANCER IS ALREADY PRESENT! Early intervention (see BB's CHEMOTHERAPY & RADIATION ATTACK METHOD, above) may help stop the spread of the cancer. It MAY bring about remission (after a LONG period of "treatment" and time).
But if you see the mole on your face and just watch it grow & fester ... it WILL eventually leach into the system & spread.
That's what happens with MLC women.
They are TESTING YOU!!!
You know what? My SIL was
EXPECTING to get her a$$ chewed and get thrown out of the house when she admitted to "inappropriate" e-mails with the OM. She was shocked when she wasn't, and it made her think (THESE ARE HER ACTUAL WORDS): That my brother was "OKAY WITH IT" ... because he didn't scream, shout, get ANGRY, and throw things!!
(Like most of you guys, he was shocked, but reacted in disbelief ... and reassured her (not in so many words, but by NOT throwing her out immediately) that he "TRUSTED HER."
Big mistake.
When you find out you have CANCER, you MUST act aggressively. Or it will spread.
It's the same with the infidelity that comes with MLC. If you don't act decisively RIGHT AWAY (setting boundaries, finding out if she's IN/OUT), then the illness will continue to grow.
An EA, if found but not destroyed, eventually WILL become a PA (if not with that guy, with another).
And these affairs (EA or PA) will cause her to question her connection with YOU, if she develops feelings for another.
And we all know where THAT leads.
Shock and awe are NOT meant to bring about reconciliation (although that CAN be a result) -- they are meant to BEGIN TREATING THE CANCER... and, ultimately, that will help YOU survive your wife's midlife crisis.
