I think a lot of constraints circle around Christina - some imposed on her by the people and situation around her and some she latches onto and boxes her self in. There were opportunities for her to chose a different path but she didn't. She is, in many instances, self-isolating and her family as well as the land and house itself supports her unfortunate decision. On the other hand, this is a safe and comfortable choice for her. That's not unlike decisions the rest of us make - big and small. It's an unfortunate human habit to stick to what we know and entrench ourselves in the role that leaves us most comfortable, even if there are brighter opportunities out there.
