It's not the same dynamic. Even when I'd met someone I wasn't clicking with - I still made an effort to make the experience pleasant and it would make the dates I was into smoother.

Also when I moved to another city was a great way to get out of the apartment since I knew nobody there.

Going solo is counterproductive if your goal is meeting new people.

A suggestion for next time: try the bar. Even if you’re not a drinker, it’s a great way to meet people, romantically or otherwise. After all, if they didn’t want to talk to random strangers, they’d be drinking/dining at home (or a table).

I would suggest dive bars. Many of the "hip" places blast music so you can't talk.
