I hope she was/is able to sleep for a bit. Rest and water sometimes can do wonders. When I was single it was all about me, I didn't really slack at work or anything but life revolved around one person and that was me and my dog. Survival and toys, the only reasons to work. Married life changes that, it suddenly is not all about you there is someone else that means more, so we change adapt and grow. Perhaps just a spring allergy thing and she will be fine in a day or two.
She got a bit of sleep and I was able to grab a few hours at that time. Will be a long day though, as she tends not to nap, even when sick.
When I travel for work, I get to eat in some nice hotel restaurants occasionally - the food never tastes as good as when in good company. Even crap food is okay in good company. A lot of people these days don't seem to acknowledge that life is better with people you care about - so they make choices to be "unattached" without knowing what they are missing.
I think a lot of it over the last 30 years has also been people not putting the effort into the relationships and then other young people see the bitter divorce side so they become gun shy. While working as a single person, most of my coworkers were either bitterly divorced or on the second or third marriage. I myself like being married, dining alone was always like I'm done give me he check I'm out of here, I think that is why I learned to cook a little bit.
Perhaps part of it is a fear of failure, which drives a fear of commitment. It is hard to get into something when only thinking about the potential for loss and suffering. Relationships are built on a type of trust and requires openness.
