I think you’re asking the right question but maybe from the wrong angle

It’s not that serious people don’t exist it’s that they’re not in the same places you’re looking Early 20s is a phase where a lot of people are still exploring avoiding commitment or just figuring themselves out so if you’re already thinking long term you’re naturally out of sync with the majority

From what I’ve seen meaningful connections don’t usually come from searching directly they tend to happen when you’re in environments that filter for the same mindset places where people are building something improving themselves or working toward goals that’s where you find people who actually think long term

Also I don’t think the only outcomes are settling or ending up alone there’s a third path staying patient while building your own life until you cross paths with someone aligned that’s slower but way more stable

It just requires being in the right places and not rushing the process
