I have to admit that his romance really triggered me deeply, but for different reasons than yours. The poor treatment and turning SA into a fetish and portraying it as a healthy coping mechanism? Yikes.

And for those saying "he is 350 - the trauma is gone", Halsin shows plenty of trauma over other events in his life that has happened centuries ago, why would something so traumatic ever go away? He has gone from trauma to trauma, and he indicates that he has not have had a moment to rest and actually deal with it all. He has been doing nothing but pure survival for several hundred years.

Speaking from experience: If you are in a constant state of emergency, your trauma does not heal. It gets pushed aside and returns with vengeance.
