Rose had lived with the Doctor for quite some time. First traveling with him for all that time and then being there in Lawrence. She was used to being irrationally snapped at and dealing with people who were practically bipolar. So really, nothing John did or said was likely to drive her off. He'd been through hell. And she knew that better than most. Losing someone you loved was hard, yes. Everyone knew that and accepted it. Losing them twice was just unfair. But three times?
