This statement need some further analysing.
Is declaration of bankruptcy something courageous and responsible?
To me it need courage to declare bankrupt, especially for a celebrity.
But definitely not being responsible. On the contrary, it is a irresponsible action.
Or maybe she was referring to being responsible to her, so that she need not have to bear those debts?
If so, she should not have said, it showed a man's courage and responsibility, and should have said it showed me that she was responsible to me, only.
