Hello, CBM, I'm new to your thread here but wanted to offer some perspective. Let's look at two of your statements:
I think the question is, what IS my primary goal. It is to reconcile, but it's also my own healing and happiness, which is a necessary component to R.
I don't want to feel like we have reconciled only to find myself living with a nagging feeling of injustice and unfairness that keeps me resentful of her forever. That's not really R. If this "fixes" the resentfulness, then to me it makes R more likely to "stick" in the long-term, even if stresses things int he short-term.
I will say, my wife and I are definitely in R and I want to make things work. This would not be intended to be an "exit event". I really don't think of it as cheating either - I think cheating requires deception and breaking clearly defined rules, and this would not be that. There would be no deception, and the rules would be laid out beforehand. Some of you feel strongly that "cheating is cheating", but you are not going to convince me to feel the same way.
However, I am willing to admit that just because it wouldn't be cheating in my book, doesn't mean it's a good idea! I have had plenty of bad ideas since d-day. I am full of bad fucking ideas and thoughts. Part of me wants to drive a thousand miles away, change my name and start over. That's a terrible idea, but I still have it. I just know I'm not going to act on that one.
So let's look at you wanting to reconcile. When I think of reconciliation, I think about accepting the reality of the past (what happened is actually what happened), managing your feelings about that reality so that you cope well with the new landscape of your M, managing your words/actions/behaviors after accepting reality, so that you are moving forward in a way that is in harmony with your goal of R, and finally, being committed to creating a new bond with your spouse that is loving, in which you cherish each other and look forward to growing old together, despite your warts, you love each other.
R is really hard because you can only control you, and your WS can only control herself. Therefore, your feelings and words/actions/behaviors are your responsibility to manage.
If you choose to allow your feelings to balloon, if you choose to not manage your emotional reactions, if you choose to stay stuck in vengeance-wanting and resentment, that is 100% on you. You can blame your wife for her shitty behavior bringing you to this low and awful place, but if you stay stuck in your feelings of anger and bitterness, needing to even the score, then this is the person you will be bringing to the table when working on R.
You are 100% responsible for managing your feelings going forward. If you get triggered, and have a bout of anger, feel moments of despair, it is so so easy to play the blame game and want to attack your WW for these feelings that well up inside of you. OK, you can blame her for the trigger, but you cannot blame her for how you handle that trigger. She cannot, literally can not, manage the trajectory of your feelings.
This is the crux of the fault vs. responsibility concept (search youtube for fault vs responsibility will smith). You have to own your responsibility for managing your feelings. You have to own your responsibility for managing your words/actions/behaviors if you want to be a healthy person and have a healthy marriage.
I think that what all the naysayers are trying to get to with advising that a revenge "affair" (or one-time pass for an open marriage, or whatever action you are contemplating) is a really bad idea, because you are contemplating a dysfunctional way of managing your thoughts and feelings instead of a functional, healthy way. By going down the path of evening the score ***you lessen yourself*** and tear down more of the fabric of your M. This will not help you R, because you will be bringing an even more broken man forward into the future with your WW. Only this time you will be the one breaking yourself. A "short term more damage" followed by "long term more healing" scenario isn't what you will get.
I will agree with you, that this idea of having sex with someone else besides your WW as a deliberate activity you would plan and execute (because your reasons) is a terrible terrible idea. I'm not blaming you for having the idea or bringing it to the board for discussion, we all have terrible thoughts from time to time. But I am saying that if you do choose this path, it will take you further away from your goal, not closer.
my primary goal. It is to reconcile, but it's also my own healing and happiness, which is a necessary component to R.
Your own healing and happiness. That would be nice, wouldn't it? I think your greatest chance of achieving this is to continue to live your life as a moral person. To continue to be faithful to your wife. To continue to strive to provide the best home for your kids. To continue to strive to be someone who can walk with a bounce in his step, proud of who he is. To be someone who recovers from a low place and climbs out to a high place. Someone who chooses to work towards happiness and healing instead of vengeance.
to find myself living with a nagging feeling of injustice and unfairness that keeps me resentful of her forever.
Respectfully, this is where your internal work lies. It is in finding yourself coping with nagging feelings and letting go of resentments, in a healthy way. There are so many other ways you can accomplish your goals. Go to therapy. Sign up for weekly sessions and keep going until you feel like you are where you want to be inside your head and your heart. Join a gym and pound on a bag. Split firewood. Train for a marathon. Take up art and draw or paint your resentment. Write poetry or songs. Arrange for time away from her with buddies, go camping, build a tree house. Go fishing. I don't know what you enjoy so I'm just throwing ideas out there, but I suggest you think long and hard about any possible alternatives that help you manage your feelings in a way that doesn't further weaken your M or your own self-image.
I will remain forever angry and resentful of my XWH for what he did to my life. Except I really don't feel those feelings any more. I just remember that I once was horribly angry and resentful, and now his actions long ago no longer have any power over me. I've moved away from that. So the anger and resentment is past. I've chosen to turn my back on those feelings and leave them behind. I've worked on becoming a better person. I've grown since my D. I wish I hadn't gone through that hell, but in the end I've made myself into the kind of person I want to be (well truthfully I still have work to do), and I'm happy.
