I think if MLC arrives in mid life as you imply and I infer that from you that WH could be in MLC additionally. Primarily I think he was a traditional systematic abuser, sadly MLC alone will not apply. I say sadly because I don't see any resolution of WH behaviour as I truly believe it's a personality issue not a behaviourally driven one.
He may have MLC issues and I hope for his sake he resolves those and obtains the help he needs to heal. I would wish this for him and all those in MLC.
I absolutely agree. You didn't break him and can not fix him.
No matter what he is or has - he must fix himself, on his own.
Yes this board is a great place for all of us to work on ourselves!
