Hi Sunny
I am sorry you are having such an awful time with this divorce.
Maybe you can just stick you "your truth," insofar as your children are concerned. You are a good mother and have good instincts. You know what is best for your children. So, stand by that and don't be afraid to voice it. So what if someone doesn't like it?
As far as role playing go, I haven't done this but T has mentioned the possiblity. OMG role playing as your husband? Wow, that could be fun. (Okay, mind out of the gutter, Miss!)
Sunny, you and your T have a fine history of working through difficult things together. Maybe you need to let him lead on this one and see where it goes. I know that when I cannot see the forest through the trees it is confusing and causes anxiety.
Just go one step at a time and stick to your truth.
Peace.
