I'm not used to this at all. Who am I living with, seriously? I know I don't have to tell anyone how strange everything feels. And I know I wasn't the easiest to deal with, but I still don't get the automatic 'switching off' thing.
None of us used to this. That is why we are here. Don't forget why you came to DB. You came here because some part of you believes in your M. The person that you are seeing right now, quite frankly, thinks the grass is greener on the other side. I would challenge you to find a DBer on this board whose spouse didn't completely turn them on their heals. I have thought the same thing as you are many of times. There is no easy fix, I wish there was. If you believe in your M, then stand up for it by being the best person you can be.
It sounds to me like you guys fight a lot. Figure out why you fight and at least get it straight in your head. At least then you will know what you have to fix long term. That might help you do your 180s.
