As I clearly have stated repeatedly, contrary to what you have written, we would absolutely respect any boundary that a parent sent for their child.

This is not the case here and what I am speaking about.

It is us who is having to set boundaries with them and we are trying to navigate that.

They actually are continuously harassing us for setting any boundaries with them based on their behaviour and cannot figure out why there is distance and boundaries there. They will not respect our boundaries when they have been clearly and directly stated to them. They are constantly trying to communicate with us asking why we are not in their lives and trying to see us, but without making any changes to their continued behaviour and being who they need to be to be in our lives.
