Same goes for some men. They'll pursue a certain type of women, and have high expectations of em, all the while being ain't shit niggas. They'll borrow their homies clothing, steal the parents car, have a little drug money in the pocket along with a quarter sack and a stolen Henny bottle.
But that's proactive ain't shit nigga though

The worst ones are the ones that just chat shit non-stop and denigrate women at every opportunity. All the while all what buddy had to do was, clean himself up, get physically healthier, develop social skills and get a job.
True, most women really don't have a scarcity mindset, cause there's an abundance of average Joe's that are willing to pursue them.
The real rejection that hurts women, from what I've witnessed, this is purely anecdotal, is when their friends are getting married and having kids left right and center, and homegirl is dealing with the same bum niggas and she isn't really moving forward in her romantic life.
It's not a direct rejection, but it's still stings nonetheless.
Usually solution to that is the same thing as for men, just focus on yourself, keep improving and inshallah it'll work out.
