Who was Athena husband when she had Annabeth?

Athena, the Greek goddess of wisdom, strategy, and warfare, never married or had children. This is part of her mythology.

The character Annabeth Chase is from the Percy Jackson series by Rick Riordan. She is the daughter of Athena and a mortal man named Frederick Chase. In the books, Athena's chosen role was as a protector and mentor to her demigod children, not as a wife or mother.
