The only reason I bought into the love from Bruce's end was because he never put Talia in jail despite the NUMEROUS chances he's had to do so. He watched Selina get thrown in jail and then moved on (it was just after No Man's Land), while with Talia, who's participated in world shaking (and damaging events, even before Death and the Maidens) has never done a day of time. I'm convinced it's because of Bruce, Nightwing didn't try and throw her in jail during "Freefall" and why Superman let her run around Metropolis as Lexcorps CEO.I never saw much of an emotional attachment to Talia from Bruce. She was somewhere between a moment of weakness and a one night stand.
I don't think it's love anymore on Talia's end or at least not how it was. Tomasi (one of her better writers in recent years) said Talia is "in love and in hate" with Bruce Wayne. I think Bruce still hopes one day, Talia will turn a corner.
