Well, maybe it's not about you not being danish, but about the danes in general. If I don't count invitations from parents and siblings, I've had dinner invitations 3 or 4 times in the last 10 years, and I was born and raised in denmark by danish parents. In my experience, danes socialize freely in broader circles while they're young and looking for a mate. As soon as they've established a family, most danes only see their family and maybe a few old friends from their youth in private. Partaking in workplace-related social events like "julefrokost" divide danes: as many danes abhor dealing with their colleagues when not paid to, as those who think it's fun. My wife has 2 close friends from her youth she sees 1-2 times a year, I've no close friends, only professional contacts and prefer it like that. Our gut reaction to family invitations usually is: Oh no, another week-end ruined, I needed that time for my project, I needed that time just to relax.

Our philosophy seems to be: Most personal relations beyond close family is a drain of time and energy that I can put to good use in my professional life. We're not as open and cordial to strangers as seems to be the US way. In most cases it not about xenophobia, we just don't care to be bothered.

I you're open, joyful and keep an open and interesting home with constantly renewed invitations and join at least a couple of local "foreninger" of your interest , you might in time attract another type of danes with a similar outlook, they're out there, but expect to use a couple of decades to establish a circle of close friends.
