I fucked a girl with a boyfriend of 3 years last weekend.

I didn't know she was dating anyone at the time. I met her at a party, flirted with her for about an hour and brought her back to my place. Once we started hooking up in my bed, she kept saying things like "maybe I shouldn't do this" even though we both knew we were about to fuck. Without even thinking, I threw out some bullshit rationalizations for her to work with and that was all it took to get the panties off. The hamster worked his magic.

Today was when I found out she had been dating someone for 3 years. Found the guy on facebook, turns out he's a complete beta. I think most girls would agree that I'm a better catch than this guy. So why am I not surprised that this chick was willing to betray the trust of her long time partner and risk her relationship the second a better option comes along?

I suppose you could argue that maybe their relationship was already falling apart, or that maybe this girl just had no morals. I can't disprove either of those things. But I think if you've taken the red pill, you already know the likely cause of this infidelity. This is just another case of hypergamy in action.
