Answer:
Directionless
Explanation:
In the context of Benny’s description, “drifting” most nearly means “directionless,” or without a clear goal, because the relationship could be moving aimlessly. Benny says that in a love story “you might get lost” or go “down some blind alley,” which suggests that the people involved are not really controlling the outcome. Benny says “to be in love sometimes you never know.” In a relationship that is directionless, the people who are in love do not know where they are going.
