Title sums it up. To a point. So last Friday I had to work at 6pm and wasn't able to get my daughter from school. Her mother knows this. I asked her via our "coparenting" app when I could get her Saturday. She says I can't. At all. Came to find out that she made plans for my daughter and made her choose those plans or time with me. My daughter chose said plans.

I showed her in our divorce decree where it spells out what my weekends are and how she's denying me my time on the first weekend in September. She went on and on (for days) about how wrong I was. She hid behind a loophole saying I had to give 48 hrs notice that I'd be taking her on my own time. I've tried literally every day this week to contact her lawyer to no avail. What can/should I do here?
