O - I used to think that way early on now I don't give a $hit. I take my girls whenever I can get them, I stop by their practices to see them when it is not my week to have them and if the XW asks me if she can drop them off early I often agree if I am not doing anything.
When you get to the point to where you do what you want to do for yourself and only yourself with no consideration for what your XW is doing then you have truly detached.
I could care less what my xw is doing or has planned when she asks me if she can drop of early or etc. The thought no longer crosses my mind In fact she did it two weeks ago as she wanted to go to brunch with her girlfriends on a Sunday afternoon.
Since I no longer desire her I could care less what she thinks I keep to myself and do my thing.
