Just don't allow her to control you LOL. If you don't want to, I don't think you have to, well you will have to some day but just not at this moment. Just tell her that you're only just getting used to it and you need time to prepare yourself and get your head around it before you want to tell everybody else?
Aaah, you probably don't understand any of that. I'm talking utter s***. Good luck anyway!
