Maybe because you dated while young and you probably were not very busy. I dated while having a child and working demanding job and often two jobs and going to grad school in the evenings and having extensive hobbies that required time etc Going on dates was in the expense of something else, usually more valuable than meeting random people. I first went on dating site in my mid 30s and received over a 100 messages in the first week etc etc just to sort through them was a chore. Then feeling bad when i declined second date etc

Dating very time consuming in my experience and it's only worth it as means to an end: to never have to date again lol It might be fun when one is not looking for s partner or is young and not too busy
