I drop in to r/theredpill from time to time.

I'm not with these bitches anymore but I could use some advice on the thought processes behind what these women were up to. Here is the scenario....

I go to a music festival with my girl, her girlfriend and the girlfriend's boyfriend. I'm solely hanging out with my girl's girlfriend; she is dressed scantily, tits poppin' out, etc.

We're walking along having a good time, she's chatting to me, flirting with all of the guys that are throwing compliments to her exposed body and she loves it.

She runs into her boyfriend and immediately starts shitting on him. "I've been looking everywhere for you! Why do you abandon me? You were probably cheating on me!"

Now, I know this bitch had no problems until she met her "significant other." All of a sudden, he was the shitheel, when in reality, she was a straight up ho.

Thankfully, I dumped the girl who employed this same horseshit abuse, my question is: What the fuck is the thought process that is threading these fucked up relationship behaviors?

Feel free to share this, in case any other poor sap is involved something like this, and any insight would be appreciated. Thanks.
