Do you have joint custody with a "jerk?" Is your ex uncooperative and difficult? You're not alone. And the task of raising a child - negotiating the details of visitation, school, money, health issues, etc. with a an uncooperative ex-spouse is, more than likely, the most difficult task you've ever faced. If your ex is a jerk, then when you say "black," she says "white." World War III erupts when you speak with him. Her maturity has regressed to the level of an eight year old. His values are so different from yours that you can't believe you ever married him in the first place. And if your ex is a jerk, then your reaction to him or her is likely to be highly emotionally charged. Your heart may race, your palms may become sweaty, you may clench your jaw or fists at the very mention of your ex's name.
