a price
A price is when you get led on by a girl for like a year, just to find out she was dating your best friend the whole time.
He dated her for six months, then she said she was seeing someone else, and it was his best friend.
She told me she only had eyes for me, then I saw her at the mall with his brother.
He even bought her a ring, then she told him she was already engaged to his brother.
