I think you are selling yourself short. I personally know people who have gotten married for the first time after 40 (and are now in their 60's) -- and are very happy.
It's not too late, and most people will spend most of their adult life above 30. The only thing that is better about being under 30 is less wear and tear on the body.
You have already figured out that money and stuff aren't the things that really matter, and that's worth a lot. I encourage you to keep looking.
Find someone who interests you, who is of similar age and experience -- someone who has also figured out that money and stuff aren't what matters. Yeah, you'll probably try multiple times and find that it doesn't work out (for whatever reason). But if you have reasonable expectations, keep trying, and honestly look for someone to give your love too, there's a good chance you'll find them.
One thing that might help is to find ways to serve others -- in a way that does not benefit you (except the satisfaction of really helping someone). Pick a charity or an organization that is doing something that interests you, but also benefits others. That could be a good way to find someone who cares about the same things you do.
Or just find a group that has events related to a hobby you have, or a sport that interests you -- anything casual and low-to-no-pressure, but is still an "in person" thing.
Worst case you do help some other people, and/or have some fun doing hobbies/sports/etc. Best case you find someone you want so spend the rest of your life with. I think it is worth the effort. so I encourage you not to give up.
