Wow. The heroine is just so passive. She's not really part of the plot at all. She's an observer.
And she's trapped with this asshole who isn't nice to her and won't even have conversations about the important things happening in his life.
Imagine if he told her about the internal politics with the wizards. Then she could help him maneuver and maybe do some political spying on the nobility side. She doesn't necessarily need powers or position to be important to the plot. But the way he treats her is demeaning.
I want her to DO something. LEAVE. Find a new love interest. Study something you're passionate about. Start a children's charity. Learn to juggle. Anything that isn't waiting around for a dull asshole to decide that you're worth treating like a person.
