Commenting on a girl's conversation, she didn't reply, but deleted that conversation? what do you think?

To tell the truth, she clearly told others that she was single, so she should want others to see her. Maybe someone she likes. But it was definitely not you, and you, at this very moment, left such a reply. Of course, she didn't want the person she liked to see such a thing, so as to avoid any misunderstanding, so she deleted it.
