I am just going to offer another possibility, but it's hard to know exactly what he's thinking. He might just be playing right into how he thinks you will react....in other words, manipulation. One time I was "going to move out" -- it's in quotes because I didn't do it -- XAH started helping me pack some stuff in the garage and loading it into my car. It was such a ploy...his entire motivation was to get me to freak out that he didn't care. Mission accomplished...that time.
I'm sure yours does care that it's ending, even if it doesn't show for one reason or another.
I always said I wanted to get my head and heart on the same page so I could leave. Like you, I finally just had to let my head drag my heart out the door. Eventually your heart will catch up.
