God dang, these really might be the best descriptions of Audrey I've ever seen in these threads. She's made it very clear herself that ennui is one of the, if not *the*, biggest issues she deals with in her life everyday. So from that standpoint her constant need to change her looks, hobbies, and attitudes towards things can be easily understood.  
It's also natural then that this would follow with her relationships with men. As you've already mentioned she lures one in and consumes him before growing increasingly bored and out of control, ditching and moving on, but with a handful of other men on the side for the thrill of casual, no strings attached sex to keep the dopamine spikes at max levels as long as possible. This behavior is bad enough on its own but what really makes her malicious is her lack of accountability, spinning things in her head and to others to appear as the victim every time, and the comical coping with which she reconciles her actions with her alleged morality. I wonder if one day it'll catch up to her and how.
