Barbra is a dumb woman who is controlled by her emotions. Falling for Bruce is as natural as a duck taking to water since Bruce is the archetypal sigma male. Bruce is a grown ass man who should know this and be in control of his own will to reject her advances because 1. He’s old enough to be her father 2. He understands the nature of women and how they’re ruled by their emotions 3. He respects Gordon and sees him as a friend. 4 he respects Dick and sees him as a son.
