Reminds me of my ex in required mediation...
In my case we were ordered to have up to 3 mediation sessions. At the first session we went through and agreed to all but a few material or financial issues. We stalled on custody and a parenting schedule. Ex was determined our son was "her" child, that's how things were in her native culture. Factoid: She was born and raised half her childhood in the state I resided in when I met her. Mediator countered, "We're in the USA, not there." (Another factoid, but I failed to mention it in the session: Her mother let her father raise her two older brothers, her mother and the abuser SF raised her and her sister. Well, I was the father of our male child, according to her parents' example then shouldn't I raise our son?) Mediator saw we were at an impasse, ended the session and said "Come back when your positions change." (We didn't go back.) She didn't want to leave at the same time as me, still posturing as the fearful stbEx, so I stayed behind until she had driven away. As she walked out the door the mediator commented to the air, "This woman has issues." After one session. Mediation failed as expected but at least I tried with good faith efforts.
