Just a couple of thoughts.
BR – On the standard answers (Liked the sex and the sense of power…)
Of the two the later is the real issue IMHO.
I’m a former cop and early on in that career a seasoned veteran pointed out something that (nearly) EVERYONE I had to deal with did: Justify their actions.
Not explain, not understand, but JUSTIFY. Make some excuse to make what they did “reasonable” or “understandable”.
Ove the years I saw numerous cases where this applied. I venture that for every 100 people I stopped for speeding, DUI, battery, rape… whatever… maybe one would simply accept their blame with no minimizing or excuse.
“Everyone speeds here on this road. I was simply staying with the traffic”
“One beer usually doesn’t impede my driving. I think I have the flu and that’s why I swerved”
“She wasn’t serious when she cried “no”. She likes it rough”
“There isn’t any victim in burglary since everyone is insured”
“He asked for it. He spilled my beer. I had to punch him”
And maybe the worst I personally heard:
“That [8-year-old] kid enjoyed it when I gave him a BJ”
The weirdest one? The guy that drove into the stationary food-truck that had been on the same spot for several years. He insisted that they must have moved it because he had been getting his lunch there for over a year, always taking the same swerve and NEVER hitting the truck. Only “logical” explanation was that the truck had been moved.
Of the two “standard” answers your wife gave one is correct, the other is an excuse. Unfortunately, the excuse is possibly what will cause YOU the most pain.
There are two reasons IMHO people cheat. Two REAL reasons:
Validation and power.
She had the affairs to validate something, and that “something” could be connected to power. Like being able to get men to have sex with her validates she still has appeal and that gives her a sense of power.
By the time your WW could rate the sex… It was too late. It’s no less an affair if OM had ED or came too quick.
For you – if you reconcile and if your WW works on her issues – realizing that her affairs were due to her deficiencies (and lack of validation and the need for power = insecurity = personal deficiencies) is easier to handle than the thought that sex with OM was in some ways better -> making you question YOUR sex.
The second point:
A post-nup is being thrown around like it’s the Solution to All.
The only solid legal-related advice offered on SI is the suggestion you have an attorney deal with all legal issues. That includes a post-nup.
If you want a post-nup then this definitely is the time to get one. But suggestions like she leaves the marriage destitute with no alimony might possibly cause more damage than they fix. Post-nups are delicate instruments and a draconian post-nup can (probably) be easily contested in court. Agreements signed under duress are easily countered, as are unreasonable divorce demands.
You most likely could dictate certain terms in a post-nup. For example; if you divorce then you get the house at a certain lower market-value or that certain funds are considered separate property. Or you could dictate that the house be her share in a divorce at full top market value, thereby minimizing whatever claim she might otherwise have to other funds.
Just be careful and don’t think a post-nup will solve all.
