My husband really resisted letting me see his accounts and the like, saying "lets just move on from this."
I explained it to him like this:
You didn't just break my trust. You obliterated it. It was this beautiful piece of glass and now it's shattered into a million pieces. What you are asking me to do is just blindly trust you again with no reason to. It is like you are asking me to put on blindfolds and piece together that broken glass sculpture by feel alone. Do you think it will look the same or be strong if I do it that way?
He admitted that he hadn't seen it that way. He then went and removed the lock on his phone, opened his email, and sat me down.
I'm sure you've done some explanation like this in your situation. If he still hasn't come around, over a year later, he likely will never come around.
You may need to start thinking of yourself.
I'm sorry you are dealing with this.
