Well, when you were just describing her looks, I was going to advise you to stay with her because she stayed with you when you had less and you may have less again one day.
But when you started recounting what she says to you, it turned my head around. Where does she get off predicting that no other woman could ever love you and what is she basing this on? If she were saying that to me, I would not have waited for a new job or living quarters to leave.
As for how to say it, Paul Simon claims there are 50 ways. Explain your reasoning and move on. But make sure she understands it is her arrogant and self-serving behavior that made up your mind, not looks.
