They Know Your Habits, Your Interests, and Your Schedule By Heart
They don't have to text you, "Where are you?" or "What do you want to do for dinner?" because they already know. And it has nothing to do with controlling or monitoring you — a great partner simply knows you inside and out and doesn't need constant reminding that you don't like tomatoes or that you take a Pilates class on Thursdays after work. They just remember.
