Class-A Husband here: He enjoys his wife saying he is no monster so much, that he wants a divorce. Holy hot garbage, Batman!
This woman hasn't seen her husband in how many years? And the first serious thing they talk about when he gets back is that he wants a divorce. Even if they "agreed" to it before, in no way has he consulted with her about her feelings of separating.
She was, in essence, a glorified house keeper for him. If that isn't husband material enough for a princess, I don't know what is.
