I think this is hard for women to understand.
As a man, one of the most traumatic aspects of all this is the shame and humiliation. It's one thing to be cheated on, but to be humiliated on top of that made me want to die. I felt completely emasculated - laughed at behind my back. My wife's entire workplace knew that this guy had been playing around with my fiancee (and they all knew we were due to marry soon). I was the joke of the office.
We tried marriage counseling. All female therapists. It was like putting fuel on the fire for me. They just don't get it.
I need to sit down with a man who's got life experience. Someone who can speak to me plainly from one man to another. Unfortunately, the field of psychology seems to be predominantly young females. This is probably driving a lot of guys like me to suicide because there's nobody to turn to. There is literally nobody to talk to. Hence why I'm writing on a forum.
Brother, I'm so sorry that you find yourself here and as I read your opening post, I could sense your pain and I relived the days in my own life as I discovered my wife's affair. As I read your posts, this one jumped out at me and I want to do what I think I tend to do well here on SI, challenge assumptions and some of our self-talk.
I think it is important to ask yourself why you have so much shame and humilitation about this whole situation. Hear me out here, oh I hate speaking in generalizations this broad, but I promise I'm making a point, men in this society are conditioned to be stoic, emotionless, the "man of the house", and our definitions of what is manly and masculine is conditioned into us thorugh mass media, churches, etc. A part of us as men have been conditioned to see our partner as a failing of us as men in some way and part of that conditioning is because the male archetype we've been conditioned that we need to be is linked to our virility as men in the bedroom, preying on a very animalistic desire to mate that exists in us all. Again, I think the shame and humiliation that is triggered from a wife's infidelity is conditioned into us and we need to learn that we don't have to carry that shame or humiliation, it is part of how we are conditioned to respond, but we can do more than our programming if you will, we are like Data in Star Trek: TNG, always stirving to be better than our programming.
It was just my observation as I read your posts that you are dealing with tremendous hurt that has not gone away. Part of me wants to tell you that I think what I said above is linked...not to say that infideility isn't traumatic, because it is, but trauma responses are defined by cultural conditioning. What one culture sees as "normal" or "accepted" could be considered traumatic...think of language, I am bilingual in both Spanish and English, with a wife from El Salvador. In El Salvador, the word "bicho" loosely tranlates to boy or your boy like "ese hombre es mi bicho" and it's common, but in other countries, it is slang word similar to how we use the word "dick" in English...say that word to a Puerto Rican and they are going to react compeltely differently than a Salvadoreño, because their culture has conditioned them to respond to that phrase differently. I know my example is a touch silly and no disrespect to my brothers and sisters from PR or mis hermanos guancos, but I hope it sort of paints the picture of the point I'm trying to get across. When we become aware of our conditioned responses to something like this, we are able to analyze them, pick them apart and make more conscious choices to respond differently. You need to be able to forgive yourself for the decisions you made to stay and to have a family with this woman. We follow our hearts and make decisions to stay that looking back may not have been the right decision. You have to ask yourself the serious question of whether you are going to honestly stay in that prison you put yourself in or allow yourself to make different choices, be they staying and healing, or divorcing and also healing.
I think that could really go a long ways towards helping you find it within yourself to forgive yourself, because you seem to have forgiven her for her part in things, but you also still harbor a fair amount of rage towards the AP this far out. I gotta ask you this, all this time that you have been ruminating on him and obsessing about what you want to do to him (trust me brother, we all get it, infidelity stirs up some strong emotions), how many times do you think he has thought about you? I mean, you may be asking yourself, but why we he think about me...that's not really a fair question...but that is entirely my point, this guy has moved on with his life, your wife has gone NC and moved out of the country, seems highly unlikely he will part of your lives unless you intentionally put him right back into your lives. You have given far too much energy and time, time that you rightfully pointed out in a post is energy and life force we only get so much of...to this man. He is living rent free in your head. I get it, he pursued a woman he knew was married and here is where I think you are struggling, your body is giving you signals that your wife never gave you the full truth. I don't buy for one second that she had enough privacy, time and access for oral sex but not enough for "The Show", adults with access to each other not sleeping together would be more of a shock than them actually doing it, which is why it is so hard to believe that story she fed you. Who he was though is in the end very inconsequential, because he was available and willing to particpate in this shit, not what the kids today would call a "high value man" to begin with. I'm by no means trying to downplay the pain and agony this man has caused in your life, but only to point out that we BHs can get into our own heads with stuff, and again, we are conditioned to hold up this idealized version of what a masculine man looks like and guys like that who are masculine, tough, rugged don't get cheated on by what we perceive as inferior men...when that runs up agains what happened, it adds layers and layers to the trauma, because it really cuts you deeper than you should allow it to cut you.
