Context is crucial, and a single card can carry various interpretations. There are no absolutes in this realm.
It's essential to examine the tangible aspects of a situation in three dimensions, or at least as accurately as possible, before drawing either a positive or negative conclusion.
For instance, if the Death card appears in connection to the feelings of an ex-boyfriend I haven't seen in years, and I still can't move on, then yes, the Death likely signifies an unequivocal end—no lingering feelings whatsoever.
However, I've also encountered the Death card signaling the transformation of someone's feelings toward a romantic situation, such as moving out of the friend zone. In this case, the change was irreversible, and there was no going back to the previous state. The "color" of the relationship had shifted definitively.
