Even if you can't somehow figure out a way to meet up with this guy in the brief window of time that you have, hold onto the feeling of finding someone mutually interested in you- I'm sure it will not be the only time.
After many hookups, my friend met his then-boyfriend, now-husband on Grindr. Relationships, and long-lasting ones, can and do happen on these sorts of platforms. Even if you're not that fortunate, you can definitely meet people and think of it as a confidence booster when you're feeling down about yourself.
