She was vulnerable to his touch

She was happy. She had just realized that she was really happy. Later that day, however, she became sad, frightened even. Eventually, she realized that the reason she was so happy about was that she was falling in love. She didn't want that. She wanted to be independent; she wanted to eat in France, swim in Egypt, dance in Brazil. She didn't want to lose a part of herself, yet again. But she did. 

He was everything she thought of, every breath she took, every hug she wanted. She had to fight for what she wanted. But she wanted him. And she didn't want to want him. But what could she do?
She decided not to give up on her dreams. But her dreams were him. They were filled with his face, with his voice, with his smile. He was perfect. But he shouldn't be. There was nothing she could do, she was vulnerable to his touch. But she shouldn't be. She tried to close her mind, she couldn't think about him. She did her best, but then, she had to close herself and, eventually, she reached a dead end, because one can close one's mind, but how does one close one's heart?
