I haven't had any 'real' dinner plans (either with other people, or indoors) since the pandemic started, but on the other hand, I have skied quite a bunch.
If it matches your risk profile, I'd personally go with the dinner plans. The ski hill will be there next year, you'll want your girlfriend to be there too.
