I suppose it is because her dad regularly tells her that is how it went. I recall her dad saying somthing to the effect of: "Please, please marry me. You are the most fantastic person in the entire world and I will worship the ground you walk on for the rest of my life." After much hemming and hawing her mommy said, "Oh, alright, fine." I'm pretty sure I have the better memory. :)
Negative. I have never told her that. Your version is the (half) correct one. I begged, I'm not ashamed of that. But your response was closer to, "There is a God! My prayers have been answered; my ship has come in. I thought you would never ask!"
