Disonnecting is a way of protecting yourself. It doesn't mean anything you don't want it to mean. Do you want your M to be over? If you don't and you are patient, then things remain to be seen. Could he file etc, etc? Sure. You can only deal with what's in front of you unless you initiate some action.
I have to tell you though, I am still legally married with no legal action that I am aware of coming in the immediate future. Does this make my odds any better? No sweetie, it doesn't. My H divorced me emotionally before he ever moved out. What does that mean? Nothing. It is what it is.
My feelings towards him have vascillated from close to far. What my feelings are vs what I show are two different things. I guess I'm just stubborn.
As far as his belief that you'd never get fed up enough, well, don't play into that. If, at some point you decide you are done (or not), do it based on your own internal yardstick, not what you think he may be thinking.
