10 Doctor Who Love Stories That Will Warm Your Heart(s)
3. The Eleventh Doctor And River Song

The Doctor has tried romance but only with River Song (on screen at least - fans have never met Susan's grandmother) has he attempted a relationship. Of course, this being the Doctor, it goes beyond a meal and a night at the cinema. The pair live out their affair in the opposite direction with River's first meeting with the Doctor resulting in her demise.
Most couples think they have problems but they should really compare theirs to the travails that the Doctor and River are forced to endure. In reality, she's the daughter of his companions Amy and Rory and let's not forget that Amy once tried to seduce the Doctor. As well as that, River was abducted as a baby and trained by a holy order to kill the Doctor. The next time the residents of Albert Square think they're having a tough time, they should check in with Steven Moffat.
With River, the Doctor has shared secrets no one else knows (well, except maybe Clara, but she seems to know pretty much everything). These include her real name and they've been on numerous unseen adventures, too. Clever, sparky, sexy and a Time Lord to boot, River is like the best bits of Sarah Jane, Romana and Rose all in one and a real woman, not a girl barely out of her teens. Not even death can keep this pair apart.
