Do you have some kind of hobby/activity that you're into? My weekend running group usually ends up at the brewery for post-run lunch. When I trained martial arts I met lots of great guys there. Not a lot of women in that particular activity, but maybe you have something else you do or want to try. I have great friends in the community band I play in. Pre-COVID I was in a ballroom dance class, there were 3 women for every man.
