Karen (not her real name) cheated on her husband twice* for her children to have better genes.
Wow. I really don't buy this bullshit. If she has a great and understanding marriage, would adoption be a choice? What about getting a donor? What if the husband said, look wife, I'm hot as shit, but you aren't and I want my kids to be pretty - let's go find an egg donor. I really don't think that would fly. In fact, husband would probably lose a testicle. Chalk one up to another double standard.
Cheating. Affairs. Some people are wired that way. Doesn't that mean there are a lot of us that are wired for monogamy?
This world is full of fucking people.
