Hello single_cat91: I don't know. I'm just a worn out old geezer. But it seems to me that in order to find friends, or romantic partners, the first thing is to get with people you have something in common with.

I always imagine that finding some kind of social activities, or perhaps volunteer work, of some sort in an area that is of interest to you would be one way at least to approach this. It could be most anything that you find to be of genuine interest to you... something you'd enjoy doing even if you don't manage to develop any relationships as a result of doing it.

Of course, not everyone you meet is going to become even a friend, let also a romantic interest. But among the "universe" of people with whom you share one or more common interests is, it seems to me, where you're most likely to find friends & lovers. The chances of striking up a romantic relationship with someone you have nothing in common with, it seems to me, is vanishingly small. At least this is my thinking on the subject... for what it's worth.
