Hello and thank you for your question.
Why do you want your wife to take a lie detector test? Did she do something that has made you doubt her honesty or credibility?
Okay thank you for the additional information. There really doesn't seem to be enough evidence here to ask your wife to take a lie detector test. Though you may have some suspicions, the examples you just mentioned could be very likely innocent. Regardless, they do not in any way, merit that she be subjected to a lie detector test. She is getting angry and no longer cares what you think, as she finds this suggestion to be disrespectful to her and extreme. Unless you have much more solid evidence that your wife has done or is doing something that is dishonest or is betraying you or the marriage, it would be best to not accuse her of wrongdoing and to never again suggest the lie detector test.
If she has a habit of lying to you, and you have caught her cheating or is someone that has no credibility that would be a different story. Otherwise, the test seems unreasonable and over the top. I would suggest that maybe you or the two of you could get some counseling around trust or communication issues. If she is not willing to do counseling with you, then it could be useful for you to understand why you distrust her to this level and to deal with your feelings about these incidents. You really need to stop mentioning this lie detector test or you are going to push her away.
