Do you and your partner cook together or separately?

A few months ago, my husband started cooking his own meals, instead of eating what I had previously been cooking (I'm vegetarian and he eats meat). This change was partly due to our different food preferences and partly because I tend to spend more on groceries and he didn't want to keep splitting with me. (Oops.)

Now, I'm curious: How do you and your live-in partner or spouse handle cooking and grocery shopping, especially if you have different tastes? Do you share meals or eat different things? If you cook separately, how do you feel about it? Do you wish you could share meals instead? I'd love to hear your experiences!
