That doesn't sound like fun at all! I'm sorry you are so unhappy. To me it still doesn't look like NPD or any other personality disorder. He sounds like an aloof emotionally unavailable guy who says stuff he thinks you want to hear to avoid confrontation. But in reality he is not that interested. Taking responsibility for your mistakes is a sign of maturity. If he hasn't mastered it yet he is probably still immature and not a good relationship material. How old are you both, if you don't mind me asking? If he is in his mid twenties early thirties he might just not be ready to settle down yet. If I were you I wouldn't contact him anymore and wait for his move. If he never tries to call you, forget about him.
