Selina
I believe that Catwoman is Batman's One True Love.
I believe that Selina Kyle is Bruce Wayne's One True Love.
I believe that Batman/Bruce Wayne and Catwoman/Batman are made for each other and are each other's true love.
I don't think that Selina Kyle was only in love with Batman's costume. I believe that she is in love with Batman as a person as well as loves Bruce.
Now more about the Modern Catwoman that started at
Batman #404 (February 1987): "Batman: Year One, Ch. 1: Who Am I, How I Come To Be"
Selina Kyle was actually inspired by Batman to become Catwoman.
according to Batman #503
Catwoman was the first person to realize during the Knightfall saga that John Paul Batman wasn't Bruce Batman.
She even said that heat pheromones was evidence that he wasn't the real Batman;she said that Batman wreaks of Biochemical attractants and told John Paul that he's almost sterile. She straight up called him out and told him that he's not the real Batman without any doubt.
She read the guy like an open book and knew that it wasn't him because the chemistry between her and John Paul Batman was absent unlike it was with her and Bruce Wayne Batman. She didn't even know Bruce Wayne's identity at the time.
That seems that she always felt a strong connection that went beyond Bruce Wayne's costume.
The Hush saga
Batman revealed her secret identity to Catwoman
Selina and Bruce were at date opera,and they seem natural with each other.
Catwoman tried to stop Batman from killing the Joker because she didn't want him to destroy himself.
She really cared about Batman destroying himself, knowing that he can't toe the line between light and dark like she can.
What attracted her to Batman was his being a crusader who fought for what he believed in. She respected him for that. She wouldn't want him to change. Batman has a dark side that he has to keep in check. How can you not after being traumatized from seeing his parents murdered. With Batman, there is a fine line between justice and revenge. Batman needs detachment to do his job. He can't afford to get all emotional because that would make him weak. I am not talking weak in the sense of he will get his butt whipped. I am talking about weak in regards to that his psyche could be overwhelmed in darkness. If he starts killing, then he will end up being the very same thing that he's fighting against.
She even tried to stop him after being shot, and he knocked her out hitting her in the bullet wounded shoulder from her being shot by Harley Quinn.
After the Hush saga,
Catwoman volume 3 #32 "It Only Takes A Night"
Selina wanted her and Bruce to go out on a real date and forget about the masks.
They looked like a typical romantic couple on a date.. She even invited him over for a nightcap and they cozied up with each other on the couch. It ended with her being covered in only a blanket when she was lying on the couch.
Throughout the volume 3 Catwoman series, she addressed Batman-dressed, Bruce when in private. She didn't see Batman. She saw Bruce Wayne.
Detective Comics #845 (August 2008): "The Riddle Unanswered"
After the prison planet thing, Selina told Bruce about she heard about his blossoming romances with Jezebel Jet and Zatanna.
She came off like she was both hurt and jealous. She accused Zatanna of moving in on her while she was gone. She seemed like she was a typical exgirlfriend who hadn't moved on. She definitely had romantic feelings for Bruce.
Heart of Hush saga
Selina was showing jealousy about Batman/Bruce in regards Jezebel Jet.
Selina went to talk to Zatanna because she heard that Zatanna and Bruce were getting closer.
She was down when she said that Bruce moved on. After Zatanna said that Selina should be happy for Bruce, Selina said that it's for her to be about Bruce that brought so much emotion into her life.
She was going to tell her how she felt about him, but she didn't get the chance. She ended up getting attacked and stabbed after being shocked by her attacker's the face which was Bruce's. Of course, it wasn't him.
At the end of the Heart of Hush saga, Bruce confessed to Selina that she's the only woman that held his heart and that he will love her always.
She was actually torn between two men - Bruce Wayne and Batman.
It seems possible that she knew that Bruce Wayne was Batman, but she waited for him to confirm it.
or
she unconsciously knew from being very attracted to both men.
I don't believe that was in love with Batman because of his costume.
I believe that she was in love with Batman because of what was behind the costume.
I actually believe that Batman/Bruce Wayne and Catwoman/Selina Kyle were made for each other. I believe that they can't exist without the other. Catwoman/Selina Kyle is the iconic love interest of Batman. They have a 70 year history.
The golden age comic versions of them married each other in the comics too. Then when the silver age comic versions were made. Then the writers dismissed the golden age versions as another reality. Bob Kane definitely created Catwoman/Selina Kyle to be the main love interest for Batman/Bruce Wayne. Like soap operas where couples get together break up and end up getting together again, Batman/Bruce Wayne and Catwoman/Selina Kyle do the same thing. They always eventually end up together in some way.
It seems to be a cycle.
Throughout her 70 year existence, Catwoman wasn't always the villain in the comics. .
Catwoman/Selina Kyle always ended up reforming and joining Batman/Bruce Wayne in the fight against crime.
She did it in the golden version, but she ended up being blackmailed into becoming Catwoman to commit crime again that led to her death.
She did it in the silver version, but she ended up being converted to bad again through some mind machine by the Joker. She was definitely in love with Batman. Batman was very pissed off with the Joker for messing up Catwoman's mind, feeling that he lost her.
It was definitely personal. (Detective Comics #569 (December 1986): "Catch As Catscan"
She did it in the modern version. Unfortunately, it was mindwipe that led her to turn over a new leaf. Even before that, she had some conscience and didn't kill and even saved lives. I think the writers did a lousy job with her character development. A lot of it didn't make sense.
It's mainly the television shows and movies that always depict Catwoman as a dangerous villain.
I think Batman the Animated series and the Batman showed Catwoman as not-so villain like.
The former cartoon series definitely showed that Catwoman had feelings for Batman and was even concerned for his safety. In the last episode,she helped him out when that big wild cat was going to tear him to pieces.
