Maria watched Arthur leave but made no attempt to stop him after he had pulled away from her.
She felt like the worst person in the world and wanted to comfort him like he had for her, but she did not know how she could, so she let him go.
She had seen the pain in his eyes, and it shattered her to see a man that was usually so confident suddenly look so broken.
It also hurt her because he was right-- part of her really was falling in love with him, and she hated it.
Maria wanted to fall in love with the type of man who was innocent enough to make wishes on coins and throw them into fountains, not the type of man who teased and embarrassed her for his own amusement.
Even still, she had come to see these last few days that there was so much more to Arthur than what she first thought.
He knew how to be there for her when she needed him, and he made sure that she was taken care of whenever it was just the two of them.
