Gaming. I’m in my 30s and the 30s was the age bracket I’ve heard where few can carry on gaming through, because it has a tendency to die here. I piss away so much time doing other things that gaming just takes a backseat. I’m not even married or have kids.
Find people for a specific thing you want to do. For example, people to comfortably talk about important shit with (the confidants), people to do activities together (the RPG party members), and people to send memes and just hang out with casually (the couch crew).
Pro tip: when looking for a life partner, you should ideally both be able to fulfill all three roles at different times and enjoy it
