Many years ago, during an argument, my wife told me she was having an affair. Later, she said that she only said it to hurt me. That rang true for me.
But I snooped anyway.
I firmly believe she is/was not having an affair and that is not a topic I want to get sidetracked on.
The mere fact she would tell such an intentionally hurtful, destructive lie during an argument is very revealing of her level of functioning. She lacks empathy and decency.
But her diary and emails contained alot of information that concerned me. Disrespectful judgments ("he never thinks of me, or the kids") and outright lies. An interesting diary entry: "I know Damocles hates me because I am smart and he has told me that he likes his women stupid, like his mother." That still brings a strong word to my mind.
Lack of empathy and decency and

a worrisome disregard for reality.
Most concerning were entries where she described telling our kids things. A few lies, but mostly analysis from her POV that did not reflect well upon me.
Straight out ASK your kids (each individually) if their mother has ever told them things about you that are weird or confusing.
"I want to help you if Mom has made any confusing or strange remarks. Let me know. I am available to talk anytime. We can go out for a snack and talk privately"And, NEVER bad-mouth or name call their mother to the kids. But, correct any/all misinformation.
As in:
"What Mom said is incorrect. I do not know why she told you something untrue."I have continued snooping and seeing DJs and an occasional outright lies throughout the years and not said a word until now. I can't confront her or my sources will dry up.
When your W is away, make a copy of her more egregious diary entries.
I am not going to put the kids in the middle of a he said/she said argument. That would only force them to choose sides.
You must help them understand that their Mom tells stories.
You can bet your life she has told the kids things that confuse and worry them.
You need to be there to help your kids understand what the facts are.
I am having trouble with the snooping issue.
Really?
You may have a much bigger problem.
Your wife could have a mental illness or a personality disorder.
Perhaps not.
Perhaps she has simply developed very bad habits.
It seems important to me because I think that I am getting to the truth of the matter in how she sees me.
This is not about you.
This is about your wife's inability to function within the boundaries of facts.
But on the other hand, it seems like she should have some privacy and outlets to blow off steam.
Telling the kids disrespectful and false things about YOU is not "letting off steam".
It is unscrupulous manipulation and machinations.
I feel I should know that she has set about destroying my reputation and harming my relationships with other people.
I am certain that there is no malice involved but a great deal of recklessness. I think she hurts a lot and is lashing out.
Here is your problem.
She is not a loving wife.
I guess I�m looking for other peoples thoughts on the propriety of my snooping�
Here is my question.
Be honest.
Do you suspect there is something 'wrong' with your wife?
If the answer is "No" ..... then, my advice is to take her out to a fine meal without the kids.
During dessert/coffee tell her that you are unhappy.
Tell her why.
"I feel disrespected by you and the things you say about me."Tell her you are open to listening to her complaints, but you will not condone her complaining about you to anyone but you.
ASK her if there is "one thing" that you do that currently annoys/bothers her.
Encourage her to talk openly TO YOU about her concerns.
Your reaction MUST BE a willingness to listen and accept her complaints as valid.
You can respond something like:
"I understand what your complaint is. Help me come up with a remedy."A weekly coffee date with your wife to discuss her complaints is an appropriate response to this.
Give this approach about 2 months.
Then evaluate any improvement or any worsening of the diary entries.
