I just emailed him and said...we would prefer not to spend Saturday with you.
I will not respond to his response, or contact him again.
Very good. He needs to know that he does NOT get to be "everything's normal Dad", part-time, while he's running full-bent away from the family. Either get yo azz back IN to the family, or do what you have to do, but you can't just keep coming waltzing back in, literally or figuratively.
