Hope - not meant nastily ...but your mindset and processing are off down some dodgy or dead end roads ..... you are limiting yourself by not expanding your perceptions - possibly assigning meaning and value to his actions/behavior and events/situations with some fallacy type thinking.

Example:He at least has more emotion now than he did 6 months ago when everything rolled off his back and it was like dealing with a robot.

I'm not disputing the fact he still cares - I'm challenging your thought process.
Does he have more emotion now - or did he have the same emotions before, but was unable to express them?

Time to self inventory - you've been damaged by the experience and have not yet healed ......
I'll try for a type of analogy - think of battered woman syndrome or a child emotionally and/or physically abused, or merely the good kid who floats under the radar when someone else in the family is causing chaos, - the usually good kid who just for some reason isn't getting enough attention turns to acting out ... a tendency to distort, and reason that any attention is better than none

While it is clear that ordinary, healthy people may become entrapped in prolonged abusive situations, it is equally clear that after their escape they are no longer ordinary or healthy. Chronic abuse causes serious psychological harm.

Not necessarily in an intentional or malicious way - but his illness has hurt and damaged you - your experiences of recent times basically mean you have been emotionally battered .... and you are not yet healed ..... if you have the suspicion something sounds "off", or your thoughts are not what you would usually consider "right mindedness" .... then they probably are off and not right minded...time to reassess your self scripts and start rephrasing your thoughts to self....trust you, trust your gut.
