Halle was an actress BEFORE Nahla and Gabriel became a part of her life. It was just plain wrong of Gabriel to try to keep Halle from working and filming a movie, especially since according to Radar, he is not working at this moment. Halle went out of her way to compromise and offered to pay him to travel with her, while she filmed so that they could both see Nahla, much like she did when she went to South Africa to shoot a movie last year. It is clear that the most important thing to Halle is her little girl, because if her career was more important, then she would not have dropped out of a substantial role in New Year's Eve and opted to take a smaller role.
