The fiance has been awfully quick to "forgive" her. If I were him, I'd be pondering what she had put him through for quite some time. She staged a "kidnapping" a week before her wedding with full knowledge that hundreds of people had already made plans to attend the wedding, spending tens of thousands of dollars on wedding gifts, rearranging schedules in some cases and caterers, etc had all made plans for today's ceremonies.
This action, which went beyond simply running away, she called police to say she was kidnapped and also cut her hair so she wouldn't be recognized.
Run away, fiance, and don't look back. Forgive, my ass.
Hopefully after it all settles the man will see more clearly. Right now he's probably just relieved she's been found.
