Here's my take on the situation. I selected the area of the bride's face and arm that was in the shadow and used levels middle and dark adjustments to get the face and chest as near as possible to match the light level of the lower part of her chest. I then used color adjustments for magenta to decrease the saturation of the magenta colored back lighting on her skin. I didn't worry too much about the magenta on her hair that much. I then used the clone tool and blur tool to blur the line that crossed her chest resulting from those adjustments. Looking at the uploaded image, her face may be a bit too bright . . .

A fill flash is about the only solution when you have darkness and a spot light. That or expose for the spot light subject and everything else is dark
