I hate to say this, but you have possibly the best situation in terms of verifying your wife's statements as anybody on this forum.
I have only posed once prior to this, but I have followed this site for a years. In your case, the answer is very simple.
Ask your wife to help you verify her statements. Simply say something along the lines of, "I want to save our marriage. I love you, but you lied to me. Help me prove your story. If it is true, maybe we can work through it."
If she is telling the truth, or at the very least, the general truth, she will go out of her way to help verify it. What does she have to lose? She said I hired an escort. If she did, then how does helping you prove her statements true hurt her anymore? If she is being truthful, you already have the truth, and the worst of it. In fact, it helps her to help you verify the truth because she will then be credible in every other area at that point.
If she deflects, then you knows she's lying. Of course, deflection will come in a variety of colors.
1. She will attempt to paint you the bad guy for not just believing her. She'll claim that she is telling the
truth and trying to gaslight you. Don't fall for it. If she claims you should trust her, ask why. Proof of
her story is simple, and if she is trying to blame to you or dodge responsibility, she is lying.
2. She will try to shift blame onto you, by stating that your relationship drove her to this point.
3. She will claim that she is incapable of providing the truth. In this case, she will be unable to contact the
escort (which is nonsense, since she could contact him to have date in the first place), or she will be
incapable of providing hotel receipts, etc...
4. She will try to prevent you from inquiring further. Basically trying to deflect you from inquiry or shift
your attention.
Basically, it comes down to this. She has the ability to provide proof. She simply needs to contact the escort with you present. She needs to provide hotel data, etc..., or she is lying. I know it is not a pleasant prospect, but you need to look at it. If you don't, you will never be able to accept reconciliation. You will always doubt, and always be miserable at some level. Do you really want to be questioning everything twenty years from now?
