First and foremost, why should I care about this character? It's important for the player or viewer to connect with the character in the beginning. Because then they care about the story and how it ends. Establishing a connection will make the decision even harder in the end for the player. In this case, perhaps she sacrificed or gave up something (maybe she left her family in another country just to be with him). Emphasize her love and commitment to him, but let her own individual identity shine as well. If you want to leave the dialogue the same then make it make sense. Maybe her husband is verbally abusive and domineering. A real control freak that slaps her if she dares to defy his will. Then her dialogue and attitude towards the situation will make a LOT more sense for the psychology behind her actions and choices. Just Google three act structure, what is character driven vs plot driven, and how to use beats in writing.
