I've learned hypergamy is in womens nature the same way men want to reproduce with as much women(I'll call it male hypergamy, I'm not sure of the right word to use), its in our biology.

When I was in my past relationship, all I wanted to do was fuck other girls when I had good, sexy, and cute girlfriend in front of me, yet I never acted on it. I also had chances to upgrade to higher SMV women but I never did because I believe its bad karma and straight up wrong to the girl im dating.

So when she branch swings, all of a sudden its not a judgement to her character, its only her nature that did all of that.

Wouldn't it be the same if I fucked other girls because her SMV dwindled or I found other girls that were willing to give themselves to me and my SMV became higher than hers? I mean its just male hypergamy and my nature at work right?
