Note: I don't think ironpony has reported yet if there might be a connection to the Pandemic.
I enjoy taking my bride out to reasonably nice restaurants and did so reasonably often before the Pandemic.
Now, except for a few errands, I want to stay home. When I am satisfied the Pandemic is less of a threat I will be delighted to go out again. (And we did so this past summer, during a local lull in the Pandemic.)
If ironpony's gf doesn't want to go anywhere because of the Pandemic, she's got my support. If the elaborate meal preparation is to relieve anxiety about the Pandemic (or any other hopefully temporary phenomena), I'd give her some slack on it.
