As I read these interactions, I don't see Jeckyl and Hyde, I see your wife as whichever one is the nasty one...and then she says something nicer because she realizes it could come back to bite her or because someone else is telling her what to say. These things she fires out at you...the nasy stuff, isn't an alien. That is actually a part of your wife. Pretty attractive hunh? I feel when you are all kissa$$ that she seems to lash out at you. When she sets you back on your heels with her nastiness and you stand up for yourself and don't seem so whipped, she gets nicer. Is it possible for you to go darker?
