I agreed to co-parenting sessions with the same therapist who spoke to the kids a few times. It was a NIGHTMARE for me - at the second session, when he realized he wasn't going to push his agenda on me, he called me some names, started yelling and stormed out. Even to this day, we speak by phone on only very rare occasions, and I'm divorced 4+ years. Brief, to-the-point emails lead us to peaceful communication.

A good friend gave me great advice - if you don't agree to whatever she is pushing, you can simply say "that doesn't work for me," or "I plan on following the court order/agreement." That's it, no explanations, no discussion. You can't make sense of nonsense - they won't hear it, no matter how rational you are.
