PLEASE PLEASE listen to me!! You do not want to do this to yourself. I know because I speak from experience.
I do not designate myself as a Madhatter in my signature line, though I have at times then edited it. I hate that designation, it makes my skin crawl. I absolutely despise that I am what I hate most in this world... A liar and a cheater.
My story is extremely long, we have been married 19 years, she has had 3 PA and 1 EA that I know of to date. I have had an EA.
My EA started a couple of years after her second PA and just after I began to suspect her of another A, which turns out to be the EA that she was having. We have enough broken baggage between us to write a encyclopedia series on how to f*ck up a marriage.
My rediculous excuses to justify my actions at the time seemed very real and easy to stomach. She was having yet another affair, and my marriage was likely over, I wanted revenge! I wanted to feel loved! and most of all I wanted to feel an emotional connection with another woman, that I so desperately wanted from my wife and was not getting. It all seemed very fair to me at the time. We carried on the EA for a year, and then things changed in both relationships. My wife suddenly became more emotionally available, while my OW wanted more, she was at a point that she wanted me to choose, my wife or her. I chose my wife and never looked back.
I thought at the time that I was loading a cannon that I would eventually fire full force directly at my wife, I assumed that eventually details of her current affair would emerge and I would have the perfect arsenal of hatred and venom to fire back at her. I was so wrong... I held onto that secret for 10 years, and it ate me up inside and destroyed any and all ability to communicate honestly with my wife.
My wife recently participated in her third PA, and this one cuts more deeply than all of the rest. I came to a realization that our inability to communicate is such a huge part of why she strays. She has very low self esteem and constantly feels the need to be reminded how pretty and sexy that she is, and unfortunately there is an endless supply of men in this world that are happy to provide. The realization that I came to is that I contributed to this recent catastrophic event more so than at any other point in our marriage. My secrets and lies had built a wall between us that broke the lines of communication. My shame and guilt depressed me and made me unavailable to her. I understand there is never an excuse to cheat and that choice was hers alone to make, and that while my actions did contribute to breaking our marriage they did not cause her to cheat. But by that same token all of those years ago her actions broke our marriage, but the choice to have an EA was mine, and mine alone.
I hate to generalize but I will a little here, so please forgive me if I offend anyone. I believe that a majority of men view the act of sex as the breaking point in an affair, whereas a majority of woman view the "Emotional" portion as the actual affair and the sex is just a by product. So to the point, I don't think you truly view an EA as an actual affair (I know I didn't at the time), while your wife will likely be just as destroyed as you were by her PA (I know mine was).
I should point out that I recently (within the past month) disclosed my EA from all of those years ago to my wife. It took a tremdous amount of kicking and screaming on my part and a ton of support and encouragement from folks here on SI to do it, and to make sure that my revelation came from a place and a desire to heal rather than to seek revenge and throw it in her face. We are still working through all of this, so I have no idea what the outcome will be, we have a very firm boundary in place that whenever she wants to discuss my A I am not allowed to bring up hers, and when I want to discuss hers she is not allowed to bring up mine. They are separate and equally devastating affairs and we deal with them separately.
At the end of the take take this little nugget of knowledge from all of this. The excuse that almost every single WS will give is that there was something in their marriage that they were not getting and went outside of the marriage to get it. You are advocating the same exact behavior despite your reasons. I understand that being betrayed leaves you feeling broken and alone, that there is a tremendous desire to lash out and inflict the same kind of pain, but when it is all said and done lieing and Cheating is still just plain ole lieing and cheating despite the reasons. Your betraying your spouses trust, and crushing their hearts whether you believe they deserve it or not. It has nothing to do with being morally superior, we are all capable of tremendously horrible things given a specific set of circumstances, it has to do with our coping skills and our ability to deal with negative things in our life in a positive manner. Bad coping skills and poor life choices are still just bad choices despite the justification. Choose to make good choices that are healthy for you and the rest will likely fall into place.
