I agree with Joe. Establish a schedule that you both agree to. Then if she wants to deviate from that schedule she has to figure out how to make that happen without your assistance. It sounds like she's using you as her personal babysitter and maybe even using it to control and manipulate you. I would put an end to that ASAP. Now if it goes both ways where every once in a while you help her due to an emergency meeting or something and she does the same for you, that is perfectly fine. That's what my XW and I did. But it sounds like your W takes and takes and takes but never gives.
