He's... overthinking this. That's a problem, because thinking is far easier than simply feeling, particularly in these situations where he's so completely out of his depth. Thinking is clear, logical, and while it's inaccurate to say he doesn't have emotions, they are different, muted. It's obvious, though, that the issue is one of experience, not knowledge.

"Thank you for being patient with me, Ned." Daneel gives a little a sigh, and leans over to give Ned a kiss. "I can see that I am making many mistakes, and for that I am sorry, but you are very important to me. I'm glad that I am able to make you happy. I am only trying to ensure that I remain able to keep you happy, but this is clearly not the way I should be going about this."
