Hi Julie, Frustrating isn't it? He does live with you, it's not like they need to call separate households or anything! I know of no camp or school that would call both parents. You see, most normal M people wouldn't give a rat's butt which parent is called first, they would work TOGETHER and help each other and keep each other informed, etc. At my D14's school (no longer can go there now as it only goes to 8th grade) it got to the point that they would always call me as my W stopped going to meetings, showing up for events, I even had to call when she was sick and wouldn't be coming in. The people in the office all knew (and liked) me and no one ever thought I would keep important info from my W, I'm not that kind of person.
This is just another case of the MLCer thinking that the world revolves around them, that they are to be the center of the universe. How dare someone even acknowledge that you are a parent to your son and not him? I'm finding now that this kind of thinking just gets worse. My W hasn't stopped acting like a spoiled 10 year old, even in the D process. She pretends that she does things because she wants what's best for our D when what is really the case is that she is doing it for HER. Don't expect any of this to change anytime soon.
