My Wh snapped out of it. "It" for him was more of a child-like sense of entitlement and selfishness that he had been wallowing in (and had been escalating) for years. In the month following Dday and especially during his attempts to mislead me ("we were just emailing each other" and "really this is all your fault") we said a lot of terrible things to each other.
I told him that I would rather be a widow than a divorcee and tried to persuade him for the good of the family to drive himself and his cheater-truck off the mountain. " Make it look like an accident so we can collect the insurance.."
Funny but now two years later I can't remember what terrible things he told me. Mostly I remember the sting of him saying he'd take the kids half the time.
But I had been living with a Class A jerk for the last 12 years. Only two of those years had he been cheating on me but the rest of the time he was a lazy good for nothing once he got home, playing computer games and watching TV all night.
I went through raising a daughter with a serious birth defect (she's doing well now) and then having her brother right before discovering my cancer. I went to work all through chemo and he did very little to help me do anything with the kids or the house. What a f-ing jerk! But I "loved him" and I respected how hard he worked at his job, etc. etc.
Something about divorce planning and being kicked out of the house for a while opened his eyes to what a jerk he had been for all those years. He resolved to become a different person, he went to therapy for a year, quit working the long hours, took over 50% of the house work and child raising and agreed to start going to church with us.
So here we are, two years later, after we have said "unforgivable" things to each other and have acted terribly to each other and, of course, he has the past that he now has.
Yeah, I'd say there's irreparable harm. To me it is the loss of trust and feeling of specialness, the huge betrayal. For him it is probably knowing that I would rather have had him dead. Despite these things we are still together and daily life for me is 100% better than it was prior to DDay. As a matter of fact he's right now picking the kids up from Sunday school and getting ready to take them AND the neighbor kids to go see Thor so I can stay home and relax. This kind of action goes a long way to help reconcile.
