Do they want a girlfriend?
If they do, not all potential girlfriends are out at places where alcohol is flowing. I think the best ones aren't
Plus, good girl friend material are going to look at the drunken recluse like he's the biggest jerk in the world.
The recluse would probably be happy if he found a girlfriend that also liked to watch Netflix and have a beer. So that's what he should look for.
You find people like that by perhaps seeing if there are any meetups in the area for people who love movies, for instance.
There's also meetups for people who like to hike, or do other active things, or enjoy food experiences, games, motor cycles and tons of other stuff.
A person can go to those with the knowledge the other people there, male and female, have something in common with you.
It wouldn't be about going out to meet women, so no stress. It's getting together with people that enjoy the same stuff. Some of them will happen to be women.....who are also looking for a boyfriend.
