Wife files D after I confronted her 2nd EA (4)

[CWOL]

Picked up S11 at baseball practice, WW sat in car and gave me the bag. She is now reneging and won't take him to pitching practice the next day because "it wasn't in the agreement," i.e. because she wanted to make the custody 54%/46% instead of current 50%/50%. That really made me upset, now I have to leave work early to take S11, or I'll have to take him late not leaving him enough time to do homework tonight. What gets me is the reason is because I'm at working making the money which makes it possible for her to enjoy this "lifestyle" of working 15 hours a week, yet I'm being punished because of an hour that I can't be there...!
Again the sense of entitlement drives me nuts.
