I need her to acknowledge the situation of living with him, and being this casual. I feel like a reevaluation of their relationship would need to be in order. Their situation goes a bit beyond just regular roommates, and perhaps its just me but it almost feels weird about him understanding that boundaries in their current relationship are very off, but doesn't seem to really to feel the need to establish more clear boundaries. He just thinks to himself "Oh she's so defenseless", and then they move on.
