Continuity mistake: The distance between Rameses and Moses alternates from elbow to elbow, to about three feet apart as the shots change when the duo are facing Sethi during the Ethiopian tribute scene.
Continuity mistake: When Nefertiri and Moses are saying their goodbyes in the cave, his shackled right hand starts to stroke the upper left side of Nefertiri's hair, but the next cut shows Moses' hand lower down.
Continuity mistake: After Rameses slaps the coin out of Dathan's hand, the shot cuts to Dathan being much closer to Rameses. Another instant cut and Dathan is further from Rameses again.
Answer: She was a woman scorned. Yes, she loved Moses, but Moses turned his life away from the royal life of Egypt (and Nefertiri's love) to be with his people, the Hebrews, and serve the will of God. These were far more important reasons to Moses than living a lush life as a prince of a people he was not connected to by blood or lineage.
