Your girlfriend Isabel is obsessive and very clingy. She has a history of being mistreated and abused in prior relationships. When she met you and noticed you weren't an abusive jerk she fell in love with you, hard. But when her possessive nature got scary and overbearing you broke up with her. Thats when she did it. She threw herself into the ocean and killed herself but instead of dying she returned from the dead even more madly in love with you. Although she is protective and possessive of you, shes is that way because she truly does love you and believes you will be together forever.
