Characterized by delay, reluctance, or hesitation; inclined to put things off or avoid action.
From Latin 'cunctari' (to delay) plus '-atory' (adjective suffix meaning relating to or tending toward). The Latin root means to linger or procrastinate, evolving into English to describe something that causes or involves delay.
If you wanted to describe the opposite of 'proactive,' cunctatory would be perfect—it's that frustrating behavior of always finding reasons to wait, postpone, or dodge decisions when action is needed.
