The majority of them don’t ever reply, the few that do put zero effort into the conversation and often just want ~~money~~ sex. Once in a while a ~~wo~~man agrees to meet then just doesn’t. What the actual fuck? How do you ~~guys~~ girls handle this bullshit?
To be fair, I heard very similar stories (see the minor edits) from my dates. Apparently, dating sites suck for both sides. Low effort, low result.
It helps your own sanity and attractivity to not generalize and act as if the other person is genuinely decent. If they are not, move on. If they are, at least you did not screw them up for the faults of other people.
Yes, lots of women are interested in actually dating, but many, like you, suspect every other person to be a horrible experience. So each side is busy with their negative expectations and fears, plays defensively. And of course, the asymmetry does not help either.
Generally, I think it makes sense to slow down or stop or change if what you are doing becomes too frustrating for you.
Or maybe my experiences don't translate well to your area/bubble/whatever. You could talk to your female friends and see what their experiences are.
