Honestly, she sounds like someone who got burned before, learned her mistakes, and now has decided to have better judgment and values and developed boundaries so that she can better her chances of having the kind of relationship she wants with men.
Which, if you switch genders, is literally no different than what 95.5% percent of the guys on this site are trying to do after their own bad experiences.
The reality is that both people need to earn it. If she wants his emotional investment, she needs to earn that. Some women think that just giving him sex will lead to his emotional investment and that’s not true, which is blatantly evident from many of the posts on this site. The pump and dump thing goes two ways, it’s not always the guys fault, IMO. And I think the article should have elaborated on that more, rather than make it seem like it’s just a bunch of guys being douchbags.
Like the article says, the guy should stand out among the players, so too should a woman stand out among the other women tindering it up out there.
I don’t agree with her that a woman has to put off sex until he invests in her, because I think part of him wanting to invest involves the sex. So getting to know her personality and getting to know her sexually gives him a better idea of whether she is worthy of his investment. That’s what I think but I’m not a guy so let me know if that’s off.
