I'm a little late on the stories. All girls? And how many are yours and hers?
Are there any that are both of yours?

Downsizing to a house (or apartment) where you don't have room to accomodate them and the BFs may be the best option. It appears you're outnumbered and outgunned.
But, if the real father will assist in being a parent, and if the grandparents cooperate, then maybe you've got a shot if they all send the same message.
However, I just saw an "Intervention" TV ad where a drunk mom lost custody of her kids and still drinks multiple (personal) bottles of Vodka a day. Straight!
