Online dating will not decline in popularity because women aren’t receptive to approaching or being approached
Women and men alike both claim to be dissatisfied with online dating and dating in general. The way to fix this would be to have more people meet in person.
However, women do not want make the approach and men are nervous to approach because of being perceived as an intrusive or a creep. Men have also heard stories online or from friends of men who have been made of fun or called harassers for trying to make a polite approach.
There are also a lack of spaces where it’s expected or accepted to approach.
So we’re all doomed to an unhappy world of online dating and nothing will change that.
