When it comes to the point where a spouse feels the need to call a private investigator, both husbands and wives call for different reasons and get different reactions.
The wife would call the investigator to find dirt on her husband and will be pissed off if there is none.
The husband will hire a PI to see if there is any infidelity on the wife’s part. He will be devastated if there is and relieved if there is not.
And they say men and women are equal.
