He sounds OCD.

Seriously.

My ex husband was OCD and went many years undiagnosed until he had a proper diagnosis.

I could never understand why the way I packed the dishwasher away wasn't right as everything had to be aligned strategically, spoons one way, forks another.

I wasn't allowed to fold laundry as the shirts weren't placed at 90 degrees.

I do realise it wasn't my ex trying to be mean. He just had these tendencies.

With his OCD tendencies there were things I did do. He couldn't handle things being out of place, like cups, so I'd make sure I had this in the dishwasher, just as an example.

It was sort of a compromise for us both meeting each other half way.

So how did I cope? We worked on an arrangement that the things that irked his OCD tendencies he had to do or not complain about the way I did it. He got to aligned the forks one way the knives another way; he folded the laundry etc.
