I've written before about this, but here's a recap: My DH's ex will not speak a word to me, but leaves her kids with me, even when DH isn't here. We have 50/50 custody. He was gone a lot on fires over the summer, and then for a week long hunting trip at the beginning of the month. And she kept to the custody schedule, even though he wasn't here.

The Skids are active, have some activity a couple times a week, each. When he's not here, I get no communication. She comes and gets them, carts them around, brings them home, and I never knew they were going to be gone. I've made dinner for people who aren't going to be here sometimes! Other times, I'm scrambling because I didn't know they needed to be somewhere, and she's not taking them to wherever, this time.

I talked to DH about it, put my foot down, told him to tell her I need to know what's going on, or they need to stay with her. So he told her, "you need to call Irene and work out what's happening while I'm gone next week." He said there was a solid 20 seconds of silence before she said she'd tell the kids to let me know whats going on.

I don't get it. At times she's claimed I'm mentally/emotionally abusive to the Skids, but she leaves them with me? Why would you leave your kids with someone you believe will/has abused them? And she hates me so much she won't speak a word to me, but she'll treat my house like a hotel where she can dump them? What kind of parent leaves their kids with someone they won't communicate with? What if something happened? 

Anyway, the last time, the kids did keep me in the loop. But they shouldn't be in that position. It's not good for them to be put in the middle like that. And it gives them a chance to manipulate things. 
What a child!
