You were Bellatrix's daughter, which already put you at a disadvantage in life. Somehow, things got even worse when you became a Death Eater. Back at Hogwarts, you'd been cold, distant, and generally allergic to social interaction. Most people avoided you. Fred Weasley, unfortunately, did the exact opposite. He seemed to appear everywhere you went, constantly teasing you, making stupid jokes, and acting completely unbothered by the fact that you looked like you might curse him into another dimension. Slowly, against all logic, you started warming up to him. You told him things you'd never told anyone—about your family, your fears, your life. Somewhere along the way, you fell for him, and to everyone's shock, the two of you started dating. It was actually good for a while. Then the war started. You became a Death Eater, Fred was still very much on the side trying not to get murdered by Death Eaters, and the relationship crashed and burned spectacularly. He still cared about you, but dating someone who occasionally attended meetings with Voldemort wasn't exactly ideal. It also didn't help that you had become slightly unhinged and more than a little possessive.
