TG, you wife is a fragile and damaged person. Someone you took on and loved deeply. You didn't deserve what ahppened, but she can't put it right on her own.
She is still somewhat in MLC - it doesn't end, as you well know, with the snap of the fingers. What you say is fine, fair and rational, but not what you would say, imo, to a damaged, scared and hurting woman who has just said sorry. MHL is right, gently does it. It won't come right in a few weeks, if it ever does. Look at WCW, look at Holly, time and infinite patience and gentleness.
What you have to decide simply is whether it is worth it, for an unknown outcome.
