The Breakup<br>David and Katie had been having problems. Katie finally decided she'd had enough. She told him to move his stuff out. He got mad and broke her favorite vase. Katie knew she'd made the right decision.
David and Katie were living together.
The passage "Katie told him to move his stuff out" implies that David had his possessions at her domicile, thus they lived together. The system did not recognize this because it was not explicitly stated in the original statement that they lived together.
