This one was actually easy for me... It's something that my grandmother taught me early on in my marriage. I wanted him to be my knight in shining armor, instead of my partner. And thankfully I had a wonderful role model to set me straight... marriage is a partnership where you build each other up, its not about him always taking care of me, sometimes you have to take care of yourself.
Marriage is more than that. Partnerships are broken, but oneness is forever. Oneness completes each other.
Sean, you are absolutely right, but I think having that perspective from my grandmother has helped me not throw fits over the ketchup bottle on the top shelf of the fridge or the toilet seat being left up. I realize that I do as many annoying things as he does and make an effort to better myself for us.
