There's not much to rebuild in a M when one or both spouses have used WMD's and blown it to smithereens.
In my case, I consider the original person I had M'ed dead and buried, as she just doesn't exist today. I can't realistically comprehend that previous person ever resurfacing either, so utterly different is this current one. No, she's gone for good, and were the old person to show back up wanting to reconcile, I'd probably think it were a ghost. As such, I could not trust it. Forgiveness is one thing, but foolhardiness is another.
