In my opinion the best thing is to keep your dignity.She is way too young to understand and no matter what you say she will look at you as the crazy wife. Sometimes it is better to save face as hard as that may be you will feel better in the long run if you remain the one who acts like the adult. I feel for you if it were me I would probably want to kick her...you know what, but ultimately it is your H who is at fault and is disrespecting you and your family.

I keep reminding myself I am strong even if I don't feel it. I know from my past this is true. I might just get a tattoo to remind me.
