I am sad sometimes that I no longer have a partner and cheerleader in navigating these difficult times. But that role/relationship ended several years before the marriage did. And now I have two fabulous kids and their mom.
I have been employed or working under contract for most of the time since the divorce. And today I'm gearing up to start a new job so that I can get some money, but more importantly so that my kids will get some money. And yes, the dinosaur will be fed and happy in the next month.
You can't control the other parent. But you can choose your response. If you can diffuse the urgency and your need to be right, smart, witty, or even a jerk, you will go along way towards lessening the drama and making things easier for both you and your kids.
During my failing marriage, I got very good at listening for the sirens of destruction (I had done something wrong) and looking for an escape or some heroic journey to fix the problem. Both in my marriage and in this relationship, that was not the right approach.
