Ian experienced extreme abuse for almost his entire life. It is no surprise that he experiences extreme dependency in his relationship with Raymond; Raymond is the first person to treat him with kindness and respect (in Ian's eyes) so of course he is going to latch on. Of course he is going to be unable to separate himself from his primary provider of emotional, physical, and material support even if Raymond is in a relationship with someone else. Also, think about it from Ian's position. Raymond decided everything - he started another relationship AFTER they were already sleeping together, and defined the boundaries of their relationship on his own, Ian didn't get any say. Raymond as the benefactor is in a position of power over Ian that gives Ian little sway in their relationship. This is literally made explicitly clear in this chapter through the bird cage analogy. Raymond views himself as Ian's keeper, and he modifies Ian and his environment to control him. Ian is literally the victim of Raymond's manipulation. Finally, although Raymond is doing the princess dirty in regards to their relationship, she's still monarchy and complicit in the oppression of the people. It's made pretty clear that the monarchy is exploiting the labor class for their financial benefit - a pretty prominent and obvious theme in this story. I don't think she's a victim you need to feel sorry for. It's made pretty clear how vapid and tone deaf the princess is by contrasting her concerns for extravagance and romance with the actual suffering of the working class.

the ONLY VICTIM HERE is the PRINCESS. Everyone is fucking around ...the uke is to blame, the seme is to blame. I dont like both of them ........╮( ̄▽ ̄)╭
