My suggestion is also to back off. Let her realize what it's like to be a single mom. Not as retaliation but as the reality of how a divorced woman with kids lives (which is what she still says she wants..right?). I suspect you will still be doing more than a lot of dads do (even the ones who are still MARRIED) so it won't be like she's got all of it on her own. Maybe my opinion isn't the best b/c I get NO support from my ex husband. He lives 30 mins away and has NEVER picked them up for sports practices, dr appts, etc. He gets them on his weekends and shows up for the glory (like when D14 got homecoming court he was the one who escorted her, but that's it he didn't help with anything else). He has watched them maybe 5 times in the past 8 years that we've been divorced when they've been sick, so I wouldn't have to take off work. So for those reasons maybe I'm a little biased when it comes to your situation.
