He's starting to, at least. It's helped that he's had a lot of different people loving him since the end of Season One. Also, he's decided that he wants Katara to love him. (Fortunately, "Southern Raiders" happens before he does what he usually does when he wants someone to love him, and he learns that's a VERY BAD idea.)
It helps a lot that he found out Azula was lying about loving him. NEVER lie to Zuko about loving him.
