How to Choose the One

I’m actively chatting with seven different guys on Grindr. They have all been super responsive and I’ve actually gotten coffee with three of them. With all these men, how do I choose THE one. Obviously, this is not sustainable in the long term. I’m all for open relationships but would like to settle down sometime you know? Or is monogamy and long term relationships not really a thing in the gay community? I feel like I spend some time with a guy, a couple of months pass, and then we mutually lose interest and ghost each other.
