At every turn my stbx is choosing to be hostile. Over simple things like collaborating on what gifts we bought for Christmas, to the schedule arrangement we have currently and her not willing to work on adjusting it (when I started on that schedule to help her/us when we were together).

Now she calls me to ask if I want to bring my youngest to the Dr's in 20 minutes or an hour and 15. No forewarning, nothing. I could've been bringing them somewhere, made plans, etc etc. She doesn't care. This is the second time she's done this. And I told her that she can't spring these appointments on me last second, which she just got hostile and said "then do it yourself."

I just...I can't get anything decent from her. Literally all I'm asking is a heads up, and for someone to co-parent in a peaceful way. I don't get that from her. I hate it, this is no way to act.
