Pretty & nice girls attract more bees. Left over will still left out till one day they change their mind.
Those girls which attached know what is love & dun wanna be lonely.

Those which still single, they have thousand of their own reason to being single or still hoping their prince charming or Mr Perfect.

"No man can be an Island" Its all depend personal mentality. Most guys/girls just dunno how to socialise & let go their ego. That is why problem created, claiming & whining they can't find their Mr/Mrs Right.

You can't please the world & every people. Why care so much. Worst case just import wife from oversea. Get out more & meet more people, exposure more with friends, remember that 50% of population are female, and they also looking for partner.

As long the girl still haven't married, you still can approach & attract her, the best man win the girl.
