A good friend of mine broke up with his girlfriend three times....they'd been childhood friends. On the third time,she said, 'no more....I will NOT let you do this to me again' and he went away. The next time she saw him, he turned up with a ring. They're now married and have two kids.
And who can forget the future King of England Prince Wiliam? He broke up with Catherine after 3 years together because he didn't think she was wife material. They were apart for 6 months...and we all know how that story ended!!
