I'm curious, have you actually looked on Meetup before saying this (that it's absolutely not an option)? Because there are meetups at almost any time of day. There are ones you can do from home as well (Zoom meetups).

You're also prejudging everyone as "not emotionally mature" before even giving people a chance. You have no idea if people at a group you've never been to, will be emotionally mature or not. You just assume they won't be. Just like you assume people who work as accountants must all be "stuck in the matrix" and have no depth to their relationships. But you don't know that. I know some very spiritual accountants.
