You miss the point. She runs off because of the revolting thought of actually going through with marrying him...
You really like to put words in peoples mouths don't you. If you paid any attention at all, the news reports are saying it was the pressure of the size of the wedding she was running from not her soon to be spouse. They have been "shacking up" for close to a year, for cryin out load. But I suppose that means nothing to you.
You just refuse to admit you know nothing about this man's character and are making wild accusations.
