Trouble before the wedding

In the book "Revenge Wears Prada" from pages 1-62 , Andy Sachs's life has been going great ever since she quit her old job with the devil, Miranda Priesly. Andy was running a magazine of her own, and she was getting married. The night before her wedding, she started to have weird dreams about Miranda. The day of her wedding came, she got ready. But, an hour before her wedding started, she found on her fiancé's pocket a letter from her soon-to-be mother in law , desperately trying to convince Max not to marry Andy.  Andy was completely desperate, her mind was filled with doubt and questions. Finally, she decided to say yes in the altar, no matter what her questions were.

Quote analysis 

"How desperately she wanted to lean in and whisper,' Daddy, I don't want to do this just yet.'" (Weisberger, 48)

In this quote, we can see that just before Andy is walking down the aisle, she's having second thoughts, because of the letter Max's mom wrote. She's feeling bad, and doesn't want to continue.

" I beseech you, Maxwell. Please do not marry Andrea. Do not misunderstand me. Andrea is pleasant...But you my darling deserve much more!" (Weisberger,12)

I wonder why Barbara doesn't want Max to marry Andy so badly. Might it be because Miranda Priesly has spoken badly about Andrea ? 

In conclusion, Andy did marry Max after all. But, she did stayed with some doubt about what the letter said. Her mind just goes back to the memory of the letter. I wonder what will happen next. Maybe Barbara will make Andy's life a living hell? Or she will cross paths with her ex boss Miranda?
