My husband and I are polar opposites--in EVERY sense of the word (except we both love to cook). The differences between us are palpable, albeit usually pretty funny, but meal time can be downright challenging.
Things were going along quite smoothly until a few years ago when I decided to become health conscious. He'd been doing all of the grocery shopping and most of the cooking--an arrangement that suited me just fine (he's an ex-chef and has mad skills in the kitchen) until I noticed we were eating red meat more often than I wanted to. I tried requesting healthier foods and if he remembered, he would oblige me but he didn't always remember. Consequently, I ended up making a grocery runs to get the items I wanted. These days we buy separate groceries and cook separately. Truth be told, we enjoy our new arrangement because it allows us more freedom of choice and reduces meal frustration.
Anyway, dh recently had a "coronary episode" and now he, too, has started watching how he prepares his meals and what he eats. I'm really sorry about the turn of events but I'm ecstatic that he is being more health conscious. The blessings of this recent occurrence are that he survived, he's on the mend and I could get really lucky and not have to spend too much of my own money on groceries anymore. Just so you know, that last comment came from my slightly evil twin :>).
Do you have different dietary preferences from your mate, spouse or children? Perhaps you're a vegan, your spouse a strict carnivore and your kids won't go near anything green. Who primarily does the shopping and cooking and how have the differences manifested themselves in your relationship/lifestyle?
