Do you really feel like you are being taken advantage of? Or are you reacting and unconsciously thinking of punitive action on your W?
The question to ask yourself at this time is, "What I DO... will it help, hurt or have no effect on the sitch?"
I would be with my kids every day if I could, but I can't. Personally, I would consider it my gain. While you may feel like a babysitter and you're enabling your W... you could simply change your perspective of having quality time with your kids...
But...
Certainly take time for yourself. If you can, try to plan at least one or two evenings out for your personal GAL activities...
Unless you feel you need to go dark for your own personal, emotional security... then just keep doing what you're doing...
But otherwise, live an "as if" life... You don't have to give your W money left, right and centre... but I don't see a problem "lending" her the money for the dentist...
