<human>: Can you give me a shortened version of the text?

In the past 6 months or so my husband has let his personal hygiene habits really slip.  He went from showering every day to once a week.  

He doesn't brush his teeth unless I remind him to.  Even then he sometimes won't because he "doesn't have time." He waits until the last minute to get up for work.  I know he's tired which would get better if he would go to bed instead of falling asleep on the couch.  He tells me I'm nagging when I tell him more than once he should go to bed. 

He won't get a haircut until he looks ridiculous.  Even then I have to make him do it.

I shouldn't have to remind an adult to brush his teeth or go to bed, should I? He says I am criticizing him and treat him like a child.

I have a low sex drive to begin with and honestly this problem does not help.  I'm not attracted to him when he is not clean.

I love this man but I worry that as he gets older this problem will only get once and he'll turn into one of those old people with BO.

I'm at a loss about how to talk to him about this.  When I've tried he gets defensive.
<bot>: Husband's hygiene going downhill fast and I feel like I have to treat him like a child.  What do I do so I don't have to nag him?
