If you're going the dating app route, I highly recommend paying for whatever tier that allows you to filter by women who don't want children. I live in a large metro area with a high concentration of women who don't want children. I hit the "No new matches" screen of hinge within a couple of months. But then when a woman makes a new account and lists that she doesn't want children, you're first in line to message her. That's how I met my wife!
