Rebirth or Final Destination?

In my eyes, Bobbie Ann Mason's short story "Shiloh" has a cliffhanger for an end that leaves the reader wondering weather Norma Jean has given herself another chance at life, or has simply ended it all together. It is clear that the life she had with her husband is over, but where does it go from there? The last scene we see is Norma Jean on a cliff by the river and we are not sure what she is doing with her arms. To me, it would make sense in the story for her to be ending her life. Where else does she have to go after she just ended her marriage that has been the basis for her life since high school? The story does not mention anything about a college education, she has already had a child that died, leaving her broken and scarred, and despite her gung-ho attitude she seems to have little going for her. She herself says that she "can't deal" with everything that is going on, so it would not be farfetched for her to end her life. To me, the tragedy of losing her child never really hit Norma Jean. Obviously she was unable to completely ignore it, but with her husband gone for long periods of time, she was easily able to put it to the back of her mind. Even when he was at home, they never really discussed it. But with him home for a long period of time, it pushed the issue to the front of her mind. She was unhappy with his inability to get back on his feet but most of all she was confronted head on by the ugly past that they had. The child, to me, seems to be the only reason they had gotten married right out of high school. An unexpected pregnancy is no way to start a healthy marriage, so instead they started a life of mediocrity and Norma Jean was always unhappy with that deep down. It would also be a plausible scenario for her to simply leave her husband and start her life anew. Start where she left off just years behind the rest of the pack. She could finally get out from under the scrutinizing eyes of her mother, and finally move past her dead child and failed marriage. Recently, she had already began the rebuilding process with her writing and exercising classes. She could go back to school, divorce her husband, and start life anew, the way she always dreamt it would be. To be honest at the risk of being too cheesy, Norma Jean has an opportunity to do whatever she wants. She has no children, and now no husband to tie her down. Yet, as the story comes to a close, I cannot help but think that she disagrees with my evaluation of her situation. It is clear that her dead child still bothers her, and her life is a huge disappointment to her. Both death and rebirth are plausible options, yet I tend to lean towards the death. I fail to see the option of rebirth when she is hours from home with the man she just left, she is broken by her years of unhappiness, and she is on a cliff alone waving her arms.
