I suppose that as the Original Poster, I should chime in too:
My wife and I play board games one night a month with another couple, which usually includes Zombicide. Other than that, I maybe get to play 3-4 times a year - at a buddy's house, or hosting my nephew over, or at the "nano-con" we organize semi-occasionally.
While I haven't gotten to paint or build terrain in over a year, I've successfully resisted pressure to get rid of my (admittedly small) collection of figures. If they stay out of sight on the workshop shelves, they don't draw the wife's attention. She's keen on "simplifying" the house, which means, mostly, getting rid of any project I'm not actively working on at that moment.
