Hey Jen

I am just going to throw this out there.  I could very well be absolutely off base here but could your husband be on the autism spectrum by chance?  Some of what you are saying sounds familiar for folk who have Asperger syndrome.  Does your husband have a diagnosis?  Does he also suffer from depression?

I am not a doctor nor a therapist.  I can totally see where you would be concerned over his hygeine.  Would he see someone for some counseling?  Have you told him that you were a little worried about his lack of bathing?  I would open up the dialogue of telling him your concerns and see what he says.  He might be unaware that it bothers you.

I wish you the best of luck.  Please come back to tell us how things go.  And thank you for your question.
