No need to say that you are a "nice guy" she'll just roll her eyes. Just tell her you have been reflecting a lot and that "things will change around here".
She'll roll her eyes at that too but a little less. The key is action. Words mean nothing to WAW's. To an NG's WAW they're just fighting words.
I know it seems that things are moving fast, but step one needs to be telling her how you feel. Not in an upset kind of way, but matter of fact. Once you tell her this have a plan of action and stick to it.
Ex: "I don't like it that you yell at me for the economy going bad and killing the business that was out of my control. I will not tolerate it. Talk to me once you want to calmly talk."
