Your X sounds like a piece of work. You get all the work and he shows at his leisure. It sure is frustrating! Good for you for not responding to manipulation.
I'm at work on break. Ah called the kids as I was leaving and told them he is coming. My 12 year old said, Mom see Dad is coming. Like I had lied. I like how he never told them he wasn't coming, made me do it. Now I don't know what to do with him.
