So basically this is Echoleaf (male) and Streamfur/star (female). Echoleaf went from loving her to finding out she was pregnant with his kits and hating her. He was exiled, and she became the leader of StreamClan. She was attacked in her sleep by her former mate and this is a dream that she has every night. They soon get back together and have two more litters, but he turns on her again and kills her after giving birth to another cats litter.
