Just try (and it will get easier, as you flex these new mental/emotional muscles) to get to place where it's more "I'm going this cuz dammit, it's THE RIGHT THING TO DO" and not so much "Let's see how SHE LIKES IT now!!"
You don't want to swing from the reactionary place of "I don't want to do that cuz it might upset her!" to the equally reactionary place of "I'll show HER!", kwim??
