Yo: I didn't mean to imply that being single means being bitter. What I meant was, people who focus solely on looks, try to change others, never lower their standards, keep chasing after the same type, and running into the same problems usually end up becoming single, frustrated, bitter, distrusting, etc. That's because they spent all their time chasing after something that doesn't exist, and trying to change them into something they're not. All that wasted time and effort is draining.
It's better to just find a decent, cute one in the near-term. Infatuation never lasts anyway. That's all the hot girls have to offer.
