I've been married 6 years now and I know what you mean. I have a 3 year old son...so I could say I bought it for him.
Anyhow, she loves you, but not your toys. She'll make you throw away your favorite shirt (or whatever you really liked) if it doesn't look nice in the house.
You'll just have to make a room your "office" then you can display your stuff.
I've been debating if I should display my two 1/48s or keep them in box. I bought them as a gift to myself...does she know I got them.....
