I wonder if this is not so much a MI thing but a male/female thing? Your comment about knowing how his back is when he walks in the room -- I think most women are just on a different wave length from most men when it comes to those things. Not justifying it, just observing that if you mention this to a group of girlfriends, I bet you'll hear a lot of similar stories.

Also, and this is where the phrasing gets tricky for me -- this seems like a two way communication problem. He didn't know you were depressed for six years and you didn't know that he didn't know. Would his actions have been any different if he had known? What would you have done differently if you knew that he didn't know?

I would also be very unhappy to learn that my partner didn't even know what my diagnosis was after so many years. I hope you guys can work it out!
