Well not everyone is lucky enough to find the right person. And the majority of those who claim they have are lying and pretending to the world. There is a very, very small pool of people who hit the relationship jackpot and a hell of a lot more who have settled and are faking or are being cheated on while they smugly judge everyone else.i think she doesn't believe in monogamy or long-term committment is because she's never found the right person. her belief system is skewed because she hasn't been good at finding the right partner for herself. i also think she's a little loopy.
