Michael Buble was so devastated following his split from Emily Blunt he underwent therapy in a bid to understand what caused the break-up.
The Home hitmaker parted ways with the Devil Wears Prada star in July, 2008 after three years together, and Buble claims the experience made him want to be a better man.
He says, “It was a whole s**tload of things. It was going through the break-up and asking myself why. I have a tendency to sabotage relationships; I have a tendency to sabotage everything. Fear of success, fear of failure, fear of being afraid. Useless, good-for-nothing thoughts.”
