I can be awkward and a little difficult, but can be made to work. My wife is not supportive of my diet but is prepared to work with me. She prepares no more than five meals a week (weekday dinners) for me. I take care of breakfast and lunch and weekend dinners. If it doesn't fit my diet, she'll primalise a serving for me.

But then she's not keen on cooking much anymore except for desserts so I take what I can get, so long as it is wheat and vegetable oil free.
