Unfortunately the laws are written in such a way that you are guilty until proven innocent.
But ... harassment usually requires a demonstrated pattern.
One single incident where you made a unadvised statement is easy to fight.
If you had said things several times that made her uncomfortable or she and she had asked you not to and you persisted, you would be serial screwed.
Is this the first and only incident cited in the accusation?

Lawyer up for no other reason than future documentation and protection.
