What phrase indicates hesitation in making a commitment?

The phrase "with reluctance" effectively conveys the notion of hesitation in making a commitment because it suggests a lack of eagerness or enthusiasm about proceeding with a decision or action. When someone expresses themselves as doing something "with reluctance," it implies that they are proceeding with an action while feeling unsure or unwilling, which directly points to a hesitation or reticence in their commitment.

In contrast, the other phrases do not indicate any uncertainty. "Out of excitement" suggests a strong desire and enthusiasm to take action, showing eagerness rather than hesitation. "With confidence" explicitly indicates a firm belief or assurance in one's decision, which is the opposite of hesitance. Similarly, "out of necessity" implies that an action is being taken due to obligation or need, rather than any hesitation or uncertainty. Therefore, "with reluctance" is the phrase that best represents hesitation in committing to something.
