What does a Zealous relationship between 2 people means?
Zealous means marked by active interest and enthusiasm. A zealous relationship would be very wound up, enthusiastic and in high gear all the time. It sounds exhausting to me. Not necessarily physical–this could refer to any kind of eager relationship. I think it would be fairly unusual for two people at the same time to be equally zealous; usually one would be a bit more intense than the other, and that role would probably rotate between them. I think most juvenile relationships would be more likely to be zealous. Just picture a couple of hyperactive ADHD people interacting, and you’ll get the idea.
