Kaffe, settle down. From an outside perspective, her email sounds totally reasonable.
You don’t need to respond at all regarding the vehicles out front, just simply address her questions regarding your children.
Don’t defend yourself!
Just respond politely and directly.
Don’t obsess on what she is thinking. How she is wrong and you are right. Forget all of it.
If you want to take FS16 do, if not don’t. Don’t defend your choice, simply state your choice.
Don’t tell her how great you are doing, or respond to her statement about “not being in a good space right now.” Show her you are fine by the tone and professionalism of your reply. If you defend yourself, or accuse her, all you will do is validate this feeling she has.
And remember, “dark” does not mean avoiding necessary conversations about your children.
You are focusing WAY too much on her. Dropped the rope? How do you define this?
