Thank you. I really myself needed that. (Can't stop laughing.)

Do you think he is under stress always, has extreme emotions sometimes, is lost in day dreams, is detached from his surroundings, etc. etc.? Anything that might make him mentally ill? Any evidence? Please do not go over extents such as using the internet for hours for him and constantly checking his messages. They (his messages, him) are NOT important as important to you as you are to yourself.

After all, it you who matter yourself most. I suggest you to talk to him about your relationship.
