[Star Wars] When did Obi-Wan come to accept he loved Anakin?

Obviously not romantically, but, when did he realize this? Was it during the Clone Wars? Because, he seemed very distant from his padawan during Attack of Clones (and prior to it, if The *Obi-Wan and Anakin* comic is taken into account), yet during the series and throughout Revenge of the Sith they seem very close. Was it during the duel on Mustafar, when he had to confront the reality of killing someone he loved? Especially considering how fondly he remembers his old friend by the original trilogy, though, even that fondness may have come later.

I imagine he always loved Anakin, even stating as much after their duel.  

After his beloved master passed, he likely developed an instant attachment to his master's 'last wish'.  Seeing as how the boy was innocent and quickly skilled probably made him endearing like a baby brother is to an older one.

Once Anakin became a teen, though, things changed.  Still, like a parent loves their rebellious teenager, Obi-Wan put up with it.

Either way, I'd say they did not truly become close until during the Clone Wars when they constantly fought side-by-side and saved one another.  After their duel, Obi-Wan knew in his heart that he loved his 'brother' but could not save him just as he could not kill him.  Maybe this is when he accepted it, perhaps going against the 'attachment' code of the Jedi.

From here, he fondly looks back at the friend/brother/apprentice he raised rather than the man he became.
