There have been several incarnations of the vigilante known as Batwoman, at least two of which were love interests to Batman.
By the age of 25, Kathy Webb was a film director and poet who had dated several prominent figures. After she married the wealthy Nathan Kane, he gave her a circus for her birthday, knowing how much she loved performing dangerous stunts. When Nathan died of a stroke, Kathy became even more reckless. She took a job offer as a secret agent for the organsiation Spyral.
Kathy was assigned with honey-trapping Batman and learning all of his secrets. To gain his attention, Kathy crafted the guise of Batwoman and publicy assisted Batman and Robin in stopping a criminal. Batman warned her that she was playing with fire, but Batwoman seduced him and he let her team up with him and Robin.
On one adventure, the Bat-couple were under the influence of some powerful hallucinogens. They imagined their minds stranded on an alien planet and their bodies huddled up in a warehouse. Thinking she might die at any time, Batwoman confessed her love for Batman. When Dr Daedalus, the head of Spyral found out that Kathy had revealed her secret identity to Batman, he blindsided her with a secret of his own: he was a Nazi-criminal and her father!
Knowing that her relationship with Batman would be tainted if he discovered her background, Kathy coldly broke up with him. It was initially believed that she was killed in action, but this was revealed to be misdirection as Kathy took over Spyral once her father died. She briefly reappeared before Batman to kill Talia Al Ghul, then disappeared, telling the detective Stick to what you do best and don't try to find me. I don't exist. It's unknown if she'll ever reappear.
Mystery of the BatwomanKathy Duquesne was the daughter of a Gotham gangster who had formed an allegiance with the Penguin. She started dating Bruce Wayne around the same time the mysterious Batwoman was making news. Batman initially suspects Kathy of being Batwoman, this theory was shattered when he saw Batwoman at the Penguin's lounge where he was dating Kathy.
In truth, Kathy was one of three women who had taken up the identity of the Batwoman. The three were friends from art school who figured out that they would cast off suspicion if they all took turns assuming the same identity. When the Penguin enlists in the help of Bane for protection, the three all don Batwoman costumes and help Batman take down the criminals. After her identity was revealed, Kathy reconciled with her father and continued to date Bruce for awhile afterwards.
