My sister is a control freak, my brother is an x-box junkie with a side of panic attacks, I have a mild OCD with a sprinkle of depression. The worse thing is my mother refused to understand it. I came from a very bigoted community, mental health problems happen always to other people, other families, and it took many years for my mom to understand there is no shame.
There is no shame.
We are different and wrong and right in our own way.
I have to clean all my purses and my wallet once a month, I kept clothes from my childhood, notebooks and colored pencils, I have to use my special spoon for breakfast or I'll be anxious for the whole day.
And my sister and I had to find a way to co-exist in the same room during our teenage years (I could keep my things if I kept them ordered and clean... my drawers underwent a trashing every 6 months... and I let her make all the decisions).
What I want to say is we are all cracked in our individual way, and yes your husband is very nice and understanding, but probably your are very nice and understanding about his issues.
