There are three levels of OCD. The first is obviously OCD, the next is aspergers syndrome and then there is autism.

Each stage is a worse manifestation of the one before, and they all deal with personal security.

Autistics lack emotional capacity, well ask yourself what the brain occupies itself with if there is no emotion. The inanimate objects around him/her.

Aspergers syndrome has the same tendencies only they are more open allowing more stimuli to be taken in and the cyclical tendencies aren’t as bad.

Then you have OCD. Well OCD basically the manifestation of a bad experience where emotion is put out of mind or criticism was taken at a young age restricting feelings.

Now ask yourself how open is your spouse? Does he have anything to hide? Basically what I am saying is get him to open up to you emotionally and the OCD will subside with time as he learns to draw on his emotions. With some people and depending on how old he is, the mind may already be in a decline basically ensuring that there is no change in behavior. However, you also have to remember that the mind is a dynamic machine and with the right changes anything can happen.

Anyways it has to do with him hiding his feelings, or not having much in the first place.

Good luck and I hope I have at least helped.
