Sit her down and tell her that you want her to be happy and you want to be supportive but you didn't appreciate being nagged and/or threatened. You have a right to go to the bathroom, and you have a right to sufficient rest for your needs, which might not be the same as her needs. You have a right to hire work out if it is too much for either of you. I'll say something, if you used that fake accent on me more than once...oh I shouldn't say fake..but if it is fake and you used it it would drive me up the wall.

If you are pulling your weight, and it certainly sounds like you are, you might have just married a demanding, unreasonable woman. There are plenty. People who have the choice, stay clear or marry with full knowledge of what the future could be.

And men and women are thought to have different responses to coming home, for evolutionary reasons. Men really want to relax once they hit the door and make sure everything is safe (and drop all keys, packages etc. at the door so arms are free to fight any intruders). Women might see the home as their base of operations, as opposed to the wild world, regardless of how engaged they are outside the home.
There is a whole book I read on this subject. Can't remember what it was though.
