How do I confront my cheating wife with dishonorably obtained evidence on her cheating?
Sorry, but you broke that “thin thread” of trust when you snooped through her private messages. If you had suspicions, you should have just addressed them directly to her and told her how you felt. There is no way to confront her with the evidence without her knowing that you went snooping, so either face the music and bust her for cheating, or try having the discussion that you should have had in the first place…honest, open conversation about your marriage. I hate to mention this, but since your marriage was arranged, there is a good likelihood that she is in love with this other man and not you. Not trying to be hurtful, just honest. I hope you are prepared for the worst when you have “the talk”. Good luck to you.
I don’t know why you’re so surprised. It’s not like you and your wife married one another out of love. You are married because both of you were too immature to stand up to your parents and say: “No, I will not marry someone you have decided is the right one for me, I will find that person myself, thank you.” The only thing you can do now is have a very frank talk with your wife, tell her that you understand she doesn’t love you, tell her that getting married was a mistake and that you want to get an amiable divorce. Do it before you end up having kids.
