I've just come to the conclusion that their mom's world is just plain and simply unhealthy for the girls.
Well...hopefully they won't have to live 50% of their lives in that enviornment without you there to protect them from her bad life choices or decisions. Hopefully you can somehow convince her to give up as much custody as possible... maybe point out that she'd have more time to date, have more "fun," be less burdened with the kids, guys will like that she's unencumbered, etc... Take advantage of the fact that this lifestyle is still fun for her, eventually it won't be. But use it to your advantage now.
Sadly, I do see kids in these situations (a parent involved in unhealthy life choices) exposed to stuff I would never want my own kids exposed to.
There is no arriving, ever. It is all a continual becoming.
