Dont send him that. Just let it be how you feel. It does not help going forward as two people trying to coparent peacefully.
I've felt the same urges to "speak my mind". Every interaction with Ed and my very selfish ex wife is a test in maintaining calmness.
BTW... Everything I have ever read that you have written does not show a woman with any selfishness. Maybe just one case of lack of judgment in kissing a guy that made you throw up.
