Sue,

In some ways he has always been like this but not ALWAYS...it's gotten worse over time and it was great when he first came home..I didn't expect it to stay like that but also didn't expect to have it turn almost back to what it was just prior to ow.

I doubt it's a medical thing and if it's a mental thing well he's not sharing any insights and prefers to just act like there isn't a problem.
