One thing most people seem to get in the context of a romantic relationship is a default dinner partner. They eat dinner together some or a lot of the time. On a day when nothing particularly unusual is happening, one knows that the other will likely be there for the evening meal. That person will be around; that person is enjoyable to be with; the two of them have a comfortable overlap in their culinary tastes; they have shared experiences to talk about.
Let's say you're paired up romantically but it's a long-distance relationship. Or perhaps your spouse is 100% solar powered and does not ever enter restaurants. Maybe you're allergic to the only food she can eat, or you've taken a vow not to eat in his presence until he learns table manners. In short, you're romantically partnered and gustatorily single. Do you eat alone? Frequently?
If so, and if you live near* me, holler.
