Really now, in ten years, Anakin has never gone back to visit his mother, even once? Are Jedi training and Padawan responsibilities that restrictive that he can't take a week off to see how his own mother, who he left behind in slavery, is going? That's the only possible reason for Anakin not to have seen his mother since the first movie, and it's a pretty damning one.
Things would be different if Anakin actually had a sensible excuse for avoiding Tatooine for the past few years. And kept in touch with his mother by radio.
Anakin: I look forward to seeing Naboo again. It's by far the most beautiful place I've ever seen...
Padmé: As long as Bubble hasn't run it into the ground.
Anakin: I doubt he's had much chance in the few days you've been away.
Anakin: I haven't seen it for ten years. Or my mother.
Padmé: You haven't even visited your mother?
Anakin: I've called, but she insists it's unsafe to visit. I'm still wanted over that misunderstanding with the Rodian boy, Greedo.
Padmé: You're a Jedi now! You could go back and kick their butts!
Anakin: Jedi uphold the law, not engage in personal vendettas.
Padmé: It must be difficult being a Jedi... not being able to beat up whoever you want... or carpet-bomb the places you want...
Anakin: Or be with the people I love.
Padmé: Love? What's that got to do with killing bad guys and taking their loot?
Anakin: A love of justice is central to a Jedi's life.
Padmé: The Jedi have changed so much.
Anakin: You haven't changed a bit.
