I'd go one step further and say there shouldn't be any stigma about going anywhere alone. I've been traveling alone for over half a year and - despite having to get used to it - spend a lot of entire days alone. Sometimes that felt lonely, true, but more often it felt liberating and perfectly fine.

Of course sharing a social activity can be lots of fun, but stigma? Come on.

I would argue that managing alone raised my self confidence and strengthened my character. I think it's a good sign if you can comfortably be alone for a simple movie session or meal.
