My cousin Shawna and this kid named Trevor were buddies growing up. At age 12, Trevor tells his mom that he is going to marry Shawna. But Shawna likes other boys, and she's really pretty, so the other boys like her. She dates a few in high school. At 18, she has her first kid and then marries the father. She has another kid with him. Her husband treats her poorly, but since they have a couple of kids, she's stuck. Then the husband hits a deer on his motorcycle and dies. Shawna is now a widow at age 23, but her friend Trevor is there to support her. She mourns her husband for as long as she needs to, then she starts to see Trevor as more than a friend. They begin to date. She and her kids move in with him. And they just got engaged.
I don't know if that's the whole story or even the true story, but it's a cute story.
