Germany seem relatively pragmatic and by the accounts I've heard want to ensure we've a fair deal with no 'recrimination' if we do leave the EU.
They have far bigger things on their mind, such as Eurozone stagflation and how much of a bill they're going to receive from the combination of the refugee / migrant crisis, the death throes of the Greek economy and the possible implosion of Portugal and Italy, both of whom are still in deep excreta.
Ah I see Italy have won some 'flexibility'. Spain may not get nailed until after their election for nakedly political purposes, and Portugal are hosed.

Look at those debt to GDP ratios of Italy and Spain, with no inflation to erode the nominal value of the debt, alongside the deficits in Spain, Greece and Portugal. Delightful.
