I relate so much. In about five weeks it will be five years since Lindsey turned to go. Greg and Lindsey only had 10 months together in this round of incarnations of Marcus and Sitara and as you wrote in your preamble, I'm pretty sure physical and romantic love with each other is rare across our thousands of incarnations.
Four days after she turned to go, we found her body. The police did, not me, when I finally dragged them to her building. She'd been dead for two days. They wouldn't let me in to see her.
