I admire the grace with which you have handled this situation. Your wife is playing some really nasty games with you. The only way to protect yourself and your daughters is to not play.
Work on being the best dad that you can be. As the girls grow, they will see that and admire you for it. At this point, the best that you can do is be the best example you can in order to counter some of the crud that your W is dishing out to your kids.
Kids like structure, even if they resist it. In time, your Ds will thank you for being Marine dad--they will always walk all over their mother.
