I really don't think Grant is a bad or controlling person. I think it's just the different ways our brains work.  
I'm no control freak but, yes, the dishwasher had to be loaded a certain way or the dishes will not be properly cleaned! If you overload the washing machine your clothes will not be clean and you will eventually break the machine.  
I don't agree with Dr. Phil when he says accept little things your partner does that you don't like. Everyone has their comfort zone. Everyone has some things that have to be right in order to keep them sane, it could be keeping the t.v. remote in a certain place, paying bills two weeks before they are due or keeping your closet in a certain order. Why should I get stressed out every single day instead of just asking my husband to please respect my feelings?  
On the other hand, there are certain things that I realize I am very anal about such as laundry and organizing, so much so, it's not fair to expect someone to do it exactly how I want it done so those things I choose to do myself. I would love to come home after work and have my husband make dinner but I know I wouldn't be comfortable with it, I would be up his butt the whole time, making sure he is putting things away where they belong, not making a big mess, not over/under cooking, basically driving us both nuts so, instead, I do it. In return, I never put anythnig away in HIS garage without asking where it goes first!
