Personally, I believe she wasn't there because it was the one that hurt him the most.
I don't really like that reasoning... you don't just stop loving someone cold just because they do horrible things. Bruce would definitely cut all ties but I'm sure he pines about her now and then.
But your right, Bruce probably can't bear to think about her. It would be too painful. Frankly, I'm a little surprised that Talia became his one true love anyway.
But it works... for me it was always Andrea or Talia.
