Just wanted to let you know how amazing of a dad you are. When a mom is as dysfunctional as your daughter's mom is, I think it's so important for them to have an adult point out what she's doing (in a sensitive amd respectful way) so that they always remember that this is not their fault.
Gaslighting, blame, and passive aggression are hard to recognize as an adult, let alone child. When people are subjected to that, it affects their confidence in all areas...work, future relationships etc. The way you are shielding them and educating them on this has literally brought me to tears.
If she was trying to physically assault them, a good parent would just stand in front and block the blows. I feel like you're actions are no different.
Every child deserves a protector like you in their lives.
