Vielma - Feisty Feline

Meow. a sarcastic undertone to this leads to so many questions. Is Catwoman friend or foe? Batman surely finds her a friendly foe as his locks lips with Selina Kyle but he again has also locked lips with Vicky Vale. Batman doesn't really seem to have a type. Vicky Vale was obviously into batman, she immediately accepted his proposal to go out to dinner and sleep with him that night. pretty easy, but she was willing to love Batman as well. She gave him everything without much challenge to Batman and that seemed to be something good for Batman as the last thing he needs in his life is more complications. 
Catwoman on the other hand is an enigma to Batman. She makes him question his life choices, whether he is to trust her or not. She also creates a challenge to him as Selina  Kyle. As Selina Kyle she doesn't go after Bruce as easily as Vicky did. She holds out, although her new persona does overwhelm him when they are at his house, she stops and has her priorities to handle before going any further with Bruce. This is the complete opposite of what Vicky and Bruce has and yet Bruce seems to be more entranced by the challenge that Selina Kyle gives him. 
While being very attracted to Bruce, Selina has her own internal issues to work out before she can continue to work on a relationship with Bruce. Her true motives with Shreck are her number one priority and she intends on making sure she gives him what he deserves and what he did to her. Selinas internal motives are in turn what are destructive to Batman. 
As Catwoman she intends to work out her master plan and kill and destroy Shreck for what he did to her as Selina Kyle, but to get to Shreck she must partner with the penguin and in turn go against Batman. Although she wants Batman out of the picture there is serious sexual tension between them. And she uses this to her advantage. Catwoman knows that Batman is truly good but that is almost what draws her in, like on the balcony scene under the mistletoe. 
Is that tension between Catwoman and Batman the same as the tension between Selina and Bruce? I t doesn't seem to be as Catwoman uses the tension to her advantage while Selina truly enjoys Bruce and wishes she could give him more, but in the end she sucks up her lust and puts her priorities first and succeeds at her master plan of destroying Shreck.
