After reading all of these pages, I have some thoughts...
First, CT, I definitely agree that there does come a point when the BS needs to decide to be all in or all out. Otherwise you are just stuck in limbo forever and no one will like that.
How R looks for everyone though, is going to be SO different. It's not only dependent on the work done by each person, but by their temperament, personality, level of trauma, etc.
I am 4 years post DDay 1. Two years post DDay 2 (no new affair, but false R due to the fact that my WH lied for those two years about having sex). Our emotional relationship is very firmly in what you would call a good R. In fact, we are very similar to what Strugglebus detailed with her marriage. We communicate very well, put each other first, have fun together, and generally make a great team. We love each other very much. HOWEVER my trauma response has been incredibly difficult to manage. After DDay 1 I was diagnosed wit PTSD. Triggers, physical manifestations, etc. After DDay 2, they have gotten worse and my IC at the time suggested CPTSD. Being gaslit for 2 years about your sex life by someone who has "recommitted" to you and spent two years "working" with you on making the marriage and family a priority, has altered me in ways that I think may be permanent. Unfortunately, this means this our physical relationship since DDay 2 is abysmal even though I DON'T WANT IT TO BE.
For me, "forgiveness" looks like not wanting to punish my partner. Which I have definitely come to. I acknowledge his work and his change. But I will never pretend to be "okay" to manage his feelings. I think perhaps that might be where we (and some others on this thread) differ from you. And perhaps the reason why is that your trauma response has calmed to the point where your triggers are very minor and can be put aside and forgotten. I can definitely see how that could be the case. For me, I have a ton of those kind of "triggers" (that are truly just something that reminds me of the affair, I reconcile that it actually did happen, and move on). Those triggers are different than a real (IMO) trigger. One that elicits a physical response or triggers an episode of anxiety or depression. I will give you an example.
Last week, I got an email from my WH (he was in the other room working). It was a screenshot of a LinkedIn message from a woman that he met in college when we were broken up for a semester. He never dated her (they were part of the same group that studied abroad but she went to a different college) and they keep in touch extremely loosely (think a Linked In message every few years and we exchange Christmas cards with her). She lives out of state and they haven't seen each since college 20 years ago. The screenshot asked if he was going to be in a certain town for a football game as she was going to be coming to that town to show her son the college. He responded no, but that perhaps if she was going, he should. She said too bad, I'm overdue to buy you a beer. End of message. He sent it to me about 1 minute after having that conversation. At first read, I thought "Oh, that's great that he's being transparent and thinking of me." Then, I thought, oh, that sentence about going where she is, doesn't read well. I know he didn't mean it suggestively, but it's not good boundaries IMO." Then, my trauma response started going. Adrenalin starts, and I'm remembering how his A started as a NJF situation. He jokes around with everyone, co-worker is attracted to him, takes everything he says as an invitation (she told him that she had a crush on his at first meeting - almost two years before making her move physically on a drunken work trip.) Then, I pondered whether or not to even say anything. After all, I didn't want HIM to feel as if he was being penalized for doing something right. Well, he walked into the room at that point. He knew something was wrong. Inquired. I halted, and then as calmly as possible explained what happened. We read his message together. He said "Oh, I didn't mean anything by that, and you know she is almost 10 years older than me." I said "Yes, but the woman you had sex was of zero threat to me looks wise either and you had no ill intentions, but because she liked you, she read into every word you said and look where that ended up." WH then said "that makes sense. I can see that. I'm giving myself a B for this interaction. Good on transparency but I'm a work in progress. Can I do anything for you right now?" Then he hugged me, my trauma response calmed, which allowed me to break into tears and let it out. He then asked me whatever it was he originally intended and left the room. All was great. He had no shame. I thanked him for his transparency and patience. I felt good for sharing. He felt good for comforting me through it.
So, long story short, do I go with every "trigger" no. But I do not shy away from sharing my feelings. And for what it's worth, the shame "spirals" are gone. Does he feel shame sometimes? Hell yes. But it doesn't bring him down into a spiral. It's a push to do and be a better human for him.
As far as the elephant of our f-ed up physical relationship, we both know that my trauma response is the problem. (Like GMC referred to, I also agree that everyone has and reacts to trauma very differently and healing those trauma injuries is truly a difficult and different journey for all.) I accept that it's my responsibility. I'm not punishing him. He knows why and accepts it. He doesn't like it, but he loves me and is deeply sorry for hurting me and our marriage, so he's patient. I do my part by continuing to find treatments, try new things, etc. That's how he knows it's not punishment for him.
Infidelity and betrayal trauma has far-reaching consequences. At this point, any changes in our marriage and behaviors are not punishments or demands (like no solo dinners with females and transparency with all things), but boundaries and acts of love and respect for ourselves, each other and our marriage. My WH is very proactive about identifying ways to help himself and me, and also feels free to communicate about any wants or needs he has. He's an equal member in our marriage and knows he's free to leave at any time, just like I am. We choose to be here, we are grateful for each other and and we've found a way that is working for us. There is no statute of limitations on trauma and its healing IMO, but I agree that there is a statute of limitations on self or spouse inflicted penance for the WS. Empathy has to return at some point or there is no hope for a marriage based on real love, which is what we both signed up for in the first place.
