I guess it depends what the girlfriend does, if she heads back to London, time to find a job in London, likewise if she stays in Aberdeen/Scotland

Although flights from London to Aberdeen and vice versa are only around £40 return with Easyjet booked a month or so in advance, so weekend trips aren't an issue really, but still not ideal!
Damn you graduation and the real world, making things tricky
