He still wanted her madly and badly, though, even after Ra's called off their engagement (which was forced upon Talia.)
The movie ignores most of the tale of woe and plucks a few elements out of it. Same thing for Talia as a character. They took a few things here and there and ignored others (like that she actually liked Batman for most of the character's existance). They ignored Ra's trying to set up Batman with Talia as well and taking over for him as well. In the movie, Bruce just comes on Ra's' radar because he ended up in one of his prisons, and he was targeted and tempted because of what he could offer to the League as a Wayne.
