I wonder if he ever looks at me and misses that too. When he looks at me now, it's like he doesn't see me. He looks at me like I'm a stranger to him...and I don't recognize him either. How does this happen to a person?
I'm sure there are times when he misses you - Maybe he doesn't want to show it because he doesn't want to 'back down', but I'm sure it passes through his mind once in a while.
Major personality changes are scary - It seems relatively common, or at least consistent. It would be nice to get an explanation for it from someone, but mental health stuff is so difficult to really pin down. Probably best not to focus on it too much and get on with your own stuff
