You literally just said it tells you nothing and then listed something it tells you.
Being on tinder doesn’t tell anything new given the context of the conversation. Any single girls that anon’s friend’s gf would consider referring to our apparently-single anon would be interested in one or both of those things whether they were on tinder or not, or they hopefully wouldn’t agree to a date.
Well it sort of depends. Using dating apps for hookups is fine, but its awful for building relationships. The ghosting alone is pretty traumatic.
I would hope a potential dating partner would also be aware of this and have a similar view. They could just say they use it for hook ups exclusively though and it wouldnt bother me.
Presumably, if you’re looking for a partner, if the potential partner is looking for a partner it’s better.
