Forgive me my crankiness, for I have THE PLAGUE, but I have actually seen this comment or variations on it more than once now:
"Isn't the Doctor meant to be mourning Rose?"
To which I can only respond: ARRRRRRGH!!!
Leaving aside that he cheerfully snogged Reinette while Rose was still travelling in the TARDIS, then left her in another universe with his half-human clone ... it has been years. Even humans move on with their lives after losing someone they care about, and Time Lords even more so since they regenerate.
It's not that the Doctor doesn't stay attached to his previous companions, but I do think the pain of losing them tends to fade even though the love remains. I wouldn't expect the Fourth Doctor to still be pining after Jo Grant, or the Eighth Doctor to spend all his time kidnapping different versions of Ace from alternate universes because he can't stand being without her. (Something the Seventh Doctor did in the New Adventures after she was killed, and it would explain a lot of the things about Ace's wonky personal timeline in the spin-offs if he did this more than once ...)
The Doctor has loved a lot of people across his eleven lives, and I'm sure part of him misses all of them, but that doesn't mean he's not going to love new people! More than one at a time, even.
