That's it. That's all you have to say. It will throw him for a loop that you haven't been thinking about him. That suddenly he's not the center of attention.
Going back to the kid analogy. When you ignore a child what do they do? Try to get your attention.
He's testing to see and be sure you are still under his control. So don't fall for it. Act "as if" you have better and more mature things to do.
His coming by the house to do the chores is another way of control. He "knows" you can't do those things because you've allowed yourself to believe you can't. Why not? Or hire someone to do them for you. Bottom line is to take away the things that show he is "needed" and he'll start to crave your attention.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
