I've seen a lot of posts lately about men's dating problems and most were written by women, not being sexist or anything but most women just can't know. The biggest problem that makes men upset is:

The average man has to put way more effort into dating than the average woman, and the results will not even be close.

Even without online dating as a factor, this statement has always been true but online dating and apps just exasperate it. This is what is making men upset, they put in some effort, try to do what society tells them to do and what women want, and still find little to no success dating.

All us men have stories about this, so I'm not going to share mine. But this simple fact is what so many women, news channels, dating coaches, etc. miss when they give out advice.
