I'm 39... I have no idea if pair-bonding
ability is impacted, to me I suspect it's more that at my age everyone else has years of
experience and knows how to share life / holidays / a household with one main significant other.
And most importantly: everyone
knows that they can do it. Because they have done it.
One of my normie bros said there's really nothing mysterious or difficult about the couple life. It's just like having a best friend with a side of lust. (But then, his wife divorced him after she caught him cheating, so who can say how good his perspectives are? That made me sad, I liked her and they were a really cool couple, it absolutely boggles my mind that she wasn't enough for him.)
What I believe long-term inceldom
does destroy, is self esteem. The bluepilled ability to
believe that you could one day be good enough for somebody, could be desired by somebody.
It's not just the 100% rejections, as much as those hurt. It's everything else. Its the daily reminders that your results aren't typical, and most people have what you want, and most of it comes to them pretty easily.
It's the normies pretending to be mad about having to spend money on domestic gadgets and shit (
"happy wife, happy life lol amirite?)
It's everyone you work with having some story about the time at university when he had to kick some foid out of bed who unexpectedly fucked him in the afternoon because the one he really wanted to fuck was coming over soon.
It's your normie friends trying to introduce you to / hook you up with single friends of their girlfriends, and you fail every time.
It's when your friends stop doing that because they know it's a waste of everyone's time.
It's seeing your normie bro get divorced for being a lying cheating cheater, and within a year he's moving in with a new foid who apparently
wants his lying, cheating, child-support-paying cheater ass.
It's seeing women flirt with other men all the damn time. It's seeing the way women look at, talk to, and treat other men all the damn time.
You come to have just zero expectations, zero hope, zero faith that any of that could happen for you. That's what long term inceldom does.
