Break up

My husband's behavior towards me since he left is like a 9th grader or maybe even a 6th grader. I remember in the 6th grade when Troy Thomas and I broke up. I threw his Skaggs birthstone ring at him and it was done. We never talked again. We had nothing. That is how Scott views this relationship. He is not able to understand that we are parents together to a beautiful three-year-old daughter. He will not do anything nice or even acknowledge I exist. This is his Asperger's brain way of making sense of divorce. His twin brother used to be friends with my sister. When his brother started dating his wife, he broke up with my sister. They were not dating but he broke up with her in that 6th grade fashion. He would not acknowledge that she even existed or that they did have a great friendship, very, bizarre behavior for the rest of us and by the rest of us, I mean the NTs, the majority of the people.
