I am going with CyLegend on this one. Marriage does not necessarily bring stability. Why do you think almost half of the marriages are ending up in divorces now? Getting married to please society is absurd. You have to do what makes you happy.
@CyLegend - About benefits, where are you going to draw the line? Should we start asking for unemployment benefits even when we are employed because its not fair that they get paid for not having a job? Its the same way. I think of it this way - "Married people get more benefits for being in a legally binding relationship and restricted freedom".
