Medusa was in a relationship with Poseidon long ago. They got caught together in Athenas temple and Athena found this disrespectful. She turned Medusa and her 2 sisters into the gorgons and Poseidon no longer saw her. When Annabeth and Percy found her she wanted to kill Annabeth because she reminded Medusa of Athena who she holds a grudge against. Percy, however reminded her of Poseidon so she wanted to preserve him as a statue forever.
Hope this helped :)
