I've only loosely followed this thread. And it's no secret I'm not in R, my WH is not and will likely never be "R material", so get the grains of salt ready :)
When reading the 1st few pages, I thought about the wound of infidelity, or the wound from the trauma of it. IMO, we can absolutely "heal" from it, get to a place where it's not a dark shadow over our every day lives. AND, I suspect that many/most/all BS will still have triggers - even years/decades after a successful R.
So, to the extent that a BS will have a forever scar that will manifest, it seems the WS is always kind of "on the hook" for that.
If my WH had chopped off my hand, I can heal from that. I can forgive. I can choose to not "let it define me", I can not view it from a victim perspective, etc. I can even "grow" and become a superhuman with my remaining hand or other limbs - things I would not have known or learned had my hand never been chopped off. However, I still can't get my hand back, and my spouse could never go back in time to undo that swing of the axe.
There will be times that the loss of that hand manifests in ways that will need help from my spouse - could be emotional triggers of reliving the moment the axe fell... could be I just can't wipe my arse bc my remaining hand is sprained. Could be a lot of things.
So, I guess I'm confused by what is meant by "climbing down off the cross".
I don't think an R that includes holding a grudge is a "successful" R. And, in some ways, no matter how "healed" the BS is from the resulting trauma, it IS a life sentence of sorts in that it seems more likely than not that there will be times the scar manifests, and in some ways puts the WS back on the cross, so to speak.
I also don't agree with the "it's not about me" or not "to" me stuff. We can rationalize bad behavior from now until doomsday. I can see a lot of ways in which my WH's cheating was NOT "about" me. That doesn't remove the myriad ways it WAS "about" me, or the ways in which anyone with half a brain would KNOW how deeply harmful it is... including my WH - who I'm confident was very much aware it would cause me a ton of pain, and very much aware it would likely lead to D, and was equally convinced I would NEVER find out (we keep those secrets because we KNOW the consequences, which includes the pain to another - hell, how many WS will wax on forever about how they lied to "protect" the BS? ). It always reminds me of the drunk driver who says they didn't think anyone would be hurt - another way to relieve their guilt, and doesn't provide much comfort to the grieving family.
And I honestly don't understand (despite a lot of trying) the having faith in myself (or I trust myself), etc. Maybe that's just bc of my particular situation. I have faith in my ability to walk (TBH, duck gathering has taken more than I thought), but not to somehow glean when he's cheating. My WH wasn't an asshole for the entire M (which is basically all cheating in one form or another). He was a royal asshole right after the sex started, but for the most part he treated me very well in our M. Just saying I don't know how one learns to trust themselves WRT a cheating partner when they were extremely skilled in hiding a secret sexual life for a VERY VERY long time. For all I know, he could have broken NC with one of his APs or in a PA today and I would NEVER know, bc it just doesn't seem to manifest in his day-to-day behavior (maybe banging someone else & lying for so long became so comfortable it just wouldn't manifest? I dunno and I don't think I want to spend any energy on that).
Anyhow, as someone not in R and not married to R-worthy material, I don't think there is any statute of limitations. If there's trust and honesty and communication, that's all we can ever ask for (in any relationship).
