Still, relationships are more than just proximity and time spent together. You can despise someone and still be caught up in the relationship. It also has to do with emotional entanglements. AH and DP are reliving their worst moments for over 200 hrs. That's an entanglement of emotions.

Yes, it may be through third parties such as lawyers, they are still relating to each other. They are still a part of each other's lives because of a 200+ hour trial.
