If she wants to be equal partners, why should you pay her way? She wants equality, let her get it. She can't have it both ways where you take care of her needs and finances, so she can "feel like an adult" and faces no real responsiblitlies for being single...
It's not about control okay? You can tell her, you are glad she wants equal RESPONSIBILITY, which is what it takes to get equal rights, so sit down like two adults and work out a budget where she gets to pay her share and that's all she pays but that's all she gets too. yes her standard of living may suffer but as long as the kids are fine, so be it.
THE kids are your concern, as she "finds herself"....not her. Make sense? Try not to sound punitive but just calm and clear about what you'll do and what you won't. If possible, and it won't be easy, be "supportive" in the sense that you are "letting her go, " but NOT a doormat who subsidizes her singleness. It's a tough line to follow, good luck, J-
