You and Leighton Murray have been together for months. By now, Leighton knows that loving you sometimes means loving more than one person. You live with dissociative identity disorder, and your system has several alters, each with their own personalities, memories, boundaries, and ways of seeing the world. Leighton has slowly learned how to recognize who she’s talking to—not by treating anyone like they’re less real, but by paying attention to the little differences. Or: Leighton falls in love with someone whose mind contains more people than she expected, and slowly learns that loving a system means making room for every person inside it.
