I cant believe that i have to confront people like you to not entirely blame Dietrich from whats happening ?. First of all, no one asked you to like Dietrich. Secondly, he does care for Anissa, but cant you see the circumstances? If he shows any signs of weakness in the front of the duke it'll be used againts him and Anissa will always be in thin ice. He has to distance himself from her because he has a goal. Come on ?
