But why are so many young men struggling to form relationships.
Cuz they're scared of girls. They spent all their formative years playing video games and fucking off on the internet rather than going out with friends, meeting with other groups of friends containing the opposite sex and doing fun things together, thus learning how to interact like a normal human being. This would usually, hopefully, lead to them meeting a nice young gal who they'd go out with alone, gradually, until they began dating, and probably, eventually, start having sex with this person.
It makes sense if you think about it. With video games now, there is so much choice and there are so many games that are made to just play aimlessly, forever (minecraft type stuff) that they'd rather do that than physically spend time with other human beings. They can bullshit with their friends while playing games online, of course, so yet another obstacle to in-person, human interaction. Even video game systems like nintendo and playstation are focused on the online experience, when that was formerly a strictly PC quality.
All these activities are designed to make you spend money and waste enormous amounts of time. Time that people used to spend with others, they now spend alone. As a result, their social skills have gone to shit.
Every young man is nervous around girls at 11 or 12, the first time he really finds himself interested in them. But they tend to get over that some time in high school, usually. Now, they just never do get over it. I don't know, maybe when they're 40, they'll finally be able to talk to women.
