I'm anticipating this same type of behavior soon. When you figure out how to handle it, let me know!!

STBX is supposed to get 4 weeks this summer, and has scheduled NO time as of yet. I already told him since he didn't get his request in on time, he'll be at the mercy of our schedules. When you pay for camp, you don't get refunded - and the kid gets mad if they miss it. Also, I rescheduled a Dr appt for DS that was originally for Easter week when his dad swore he would have him. Never materialized, and there's a 4 month wait list for this specialist. So, the last week of August is out. Like I should live my life to accommodate my stbx. NOT ANY MORE!!
