You can keep playing around on Tinder and the like. Or you can get on with your life and living and engage with people who are equally engaged with their lives. You need someone who's happy and thriving on their own. Who wants a relationship, but only when it's right. You need someone who is not wasting time chatting online with super-attractive partners who are 10-years younger.
Sure, In online dating we all want to put our best foot forward, and make younger and prettier partners desire us, but if we're all doing that, if we're all being inauthentic... Well, that's part of the problem.
What does it look like when you are happy? What are you doing? If your best case scenario involves continuing to do that (play tennis, in my case) then perhaps you need to look into participating more. The apps are okay for spreading your reach and resetting your ambition, but you need to be doing your dream first, then the right person might come along beside you on a bike ride and say, "Hello."
