Do you think my husband has a mental problem?

I am very worried about my husband, I don't know whether he has a mental problem. He is definitely a jeckyll and hyde character, but in conversation he said that he deals with situations by creating lots of boxes in his brain where he keeps different sides of his personality and numbers them so when he needs a particular one to deal with a situation, he brings that one out. I said that we all have different sides to us which we bring out to deal with certain situations and people but I wouldn't go as far as numbering them, he replied "thats because I am structured and you are not". He has no friends who come to the house, yet he is very social at work. He says he needs a few days a week on his own as he needs peace and quiet and any situation however trivial stresses him. If I touch my feet, I have to wash my hands, everything must be clean otherwise he is stressed. He has his flat where he stays 3 days a week which resembles a clinic, everything is symmetrical and painted in white.

As everyone knows anyway, all husbands are mental
and this guy of yours has gone a little overboard with the clinical cleanliness stuff and the bookwork in his head.
He is unlikely to change whether or not a doctor decides that he has a disorder of some type.
You have to question yourself whether or not this is the way YOU want to live YOUR life. 50% of your nights are spent alone, the days he is at work, so that leaves you 3 or 4 evenings to enjoy his cleanliness fettish.
If you can, give it up - seek another life.
