He is extremely arrogant.

Explanation:

In this passage, we can tell that the speaker is extremely arrogant. He talks about his "last Duchess," who is the woman he was previously married to. And he complains about the fact that, even though many things about her bothered him, he felt he could not complain about them to her because she would not listen, or would make excuses. He claims this with an authoritative and patronizing tone. Moreover, he tells us that she smiled at everyone, and that this bothered the Duke so much he forced her to stop smiling forever. This shows that the Duke is arrogant and controlling.
