Truth About Deception

I read my wife's emails. I shouldn't have. I was suspicious about her behaviour and had to know for sure. I found out that she had been seeing another man last year, a man who was a mutual 'friend'. When I had asked her directly in the past she had said they were just friends. I felt betrayed. I had to confront her about it. I told her that my sister had found out about it. She didn't believe me. Accussed me of reading her emails. I lied. Swore black and blue that I didn't read them. I feel so guilty for reading them. She should be the one feeling guilty for seeing him and lying to me about it.
