Boy was he QUACKING in that email, roflmao
I do have a suggestion. Do you perhaps have a trusted friend that could read any email you get from him to see if it is about the children and if not the friend can just delete it. I realize that with kids you do have to have some communication, but this might be a way for you NOT to have contact with him about ANYTHING but the kids.
Just a thought. Thought maybe that might help for you to not have to read all his QUACKING, and be able to continue on with making a good life for you and the kids.
