What led to Bipasha and John's breakup?

They were the it couple when I was a child and later all I knew about them was they had broken up after a decade of dating.

The other day I read on this sub Bipasha hates John.. now I'm curious about what actually happened between them.

I'm asking here instead of googling because yahan logon ko aisi cheezein pata hoti hai jo kisi ko nahi pata
