Occasionally not having clarity and letting others decide is natural, and not problematic. But if it’s your default setting, then it’s a sign of too much niceness and low social power. Over time it can irritate and repel others and backfire as most people-pleasing strategies do. This is because always letting others decide puts the responsibility on them. They now have to decide for themselves and for you, but they don’t really know where you stand because you don’t share. This creates frustration, annoyance, and a desire for less contact.
