I don’t think Talia is even aware of Selina, and vice versa, in the New 52? I don’t really keep up to date these days… D: (Please enlighten me if they are, ‘cause that would be fun(ny))
That said, in the past Talia has stated that of all the women Bruce has been involved with, it’s her and Selina he loves most. But Talia’s actions in Gotham City Sirens, ordering Zatanna to wipe out Selina’s memories of Bruce (after Selina was kidnapped to manipulate her into revealing Batman’s true identity), signifies some kind of resentment and fear. On the other hand, earlier in Batman: Hush she shrewdly observes and dare I say acknowledges Bruce’s feelings for Selina.
If we look back even earlier at the Pre-Crisis comics, there is a lot of yoyoing going on. Selina does get visibly upset seeing Talia and Bruce together, with Robin (!) trying to comfort her.
In another instance, Selina and Talia actually worked together with Bruce …
… and quite amicably at that. (This is one of the most disconcerting yet charming pages I’ve seen)
Ultimately, Selina and Talia each play different parts in Bruce’s life. Their "tolerance" for each other largely depends on the writer’s intentions, which tends to err on the baffling side when it comes to Talia especially, I think—which is disappointing because I quite like Talia in her own right. I don’t think there’s hate precisely, just antagonism created from dramatic circumstances. And certainly there’s a dose of jealousy too.
As for the differences between the Bat/Cat and Bat/Talia relationships, it’s rather like comparing apples with oranges, isn’t it?
Plus, I really don’t want to start a shipping war—I still carry the scars from other fandoms! I suppose if I’m flippant one main difference is that Selina does not inherit an evil league of assassins led by her supervillain of a father (!).
But I’ll broaden my answer by highlighting what makes Selina a cut above all of Bruce’s other romantic interests. Because this is a BatCat blog, and I can. :P
Notably, Bruce and Selina have the longest history together, since day one, which gives them credible iconic status above all other pairings. We are lucky to have over 70 years of BatCat in all its colourful and nuanced iterations, be that in comic books, animations, to live action TV/film. But I think the difference above all differences is the fact that Bruce chose Selina as his wife, and she him.
Yeah, but what does that mean? And hang on, wasn’t that all retconned? That doesn’t apply anymore.
Well, actually they’re still around. But it underlines several things. That Bruce and Selina consider each other equals in all respects. It means two exceptionally traumatised, guarded and lonely figures can find profound solace and humanity in each other, and make such a commitment to each other. They trust each other to let all their inhibitions go. There is no coercion, no ulterior motive—they literally unmask in front of each other.
And yes, on Earth 2, Bruce willingly waits for Selina while she does time in penitentiary; he retires as Batman; he and Selina marry and have a daughter, Helena, and together they enjoy a period of great happiness (unfortunately cut short by Selina’s death).
Despite all of Selina’s mischief and criminal ways, Bruce always lets her go. Why? Why does he pamper her so? What is it about Selina that makes her the exceptional ‘bad girl’?
1) Selina surprises Bruce (often in the most delicious ways):
2) Selina brings excitement into Bruce’s dreary life.
3) They can even do normal romantic couple things like dating.
In costume …
… or out.
4) Selina keeps Bruce humble:
5) Selina understands the burden:
5) Selina gives Bruce hope.
For humanity …
… or a happier life.
6) Selina and Bruce are partners … no matter what either tries to deny.
I don’t believe any other character can fulfil all of these aspects so well and so naturally as Selina. Talia, Vicki, Silver, Shondra, Vesper, Zatanna, Diana, Sasha … they do not have such open access to Bruce and Batman the way Selina does. She is the only woman who can accept every part of Bruce. And Bruce—for all his immense wealth, intelligence, and prowess—really is helpless when it comes to falling in love. As he himself admits, only one woman really holds his heart—that one woman is Selina.
So, time and time again writers will experimentally or desperately pair Bruce up with other women. There may be retcons, reboots, temptations, mind-wipes, amnesia, pseudo-deaths, parallel universe crossings/trappings or time travel, but at the end of the day it’s always the love story between Bruce and Selina, Batman and Catwoman, that endures the test of time.
