>>102377Dating apps are okay (not great but okay) as long as you know what you're doing. Maintain low expectations and don't put all of your eggs in one basket. A lot of men will swipe right on everyone regardless of whether they actually like them because they're after sex not a relationship, keep that in mind.
To me it sounds like that guy sent his friends after you to snap a candid shot to see if you were actually cute irl, maybe?
