TITLE: Why do women have a neediness for a first love??
POST: I was curious if there was any content/articles and wanted opinions on what seems to me like a female need to be with the first guy they're intimate with..Ive personally seen and been on both sides of this before and it seems apparent that this is commonplace in almost every situation, so basically I want to know what's up with that

I admit I've always wondered this but especially lately based on my own situation..My ex of many many years ago seems to continuously bash me on social media and alludes to the "misery" that was our relationship, so much so she needs to let everyone know this all the time..Funny enough, she has a boyfriend and has been with him for a few years as well

With that it brings me to my confusion on this subject in a few ways, like why is it after so long does she seem to spend her entire day quite frequently hating me, it seems a bit excessive..Most young relationships are very high tension and i moved on long ago, but I have to say it's really weird when she still has to have this odd resentment (or secret wanting) of me after so long, I don't mention her or discuss her in any way, but lately the content has ramped up so much that it's actually starting to become agitating..Essentially I want to know if s this a common thing that women do

Even worse it confuses the shit out of me why her boyfriend doesn't seem to care..I was laughing about this the other day but in a way it's almost awkward when I think about it, they've been together for so long and her primary focus is on hating me instead of him, so on the same point why would a guy not find that weird at all..If the girl I'm dating is doing that after a few months I'd be concerned, but after a few years I wouldn't be involved anymore because it's pretty fucking weird to me..I mean if I want to tell her to get over the shit how does he not feel that way when it's his girlfriend
TL;DR: 
Why do women always have a thing for the first love they have..My ex has spent years hating on me on social media, despite having a boyfriend, what I did years ago seems to be her biggest issue
