My world, my choices, my love...

It is a few days away from both my trip and my loves...we will be just a few states away, dealing with our families and all the love and all the trauma that they give.  We will be eating wonderful food, sharing laughter with the people from our lives, re-connecting with the past...While we are apart, I know that I will be wondering if everything is ok, if she is thinking of me and if she misses me as much as I do her.  I know that we are in for a rocky road as she is so worried that in the 5 days when she is gone if there is any possibility of her losing me...How do I say no, how do I tell her that I am crazy about her and it will be 5 long days but I know who I am coming home to...

How do you convince someone whose heart has been broken before that the same future she sees is the same future that I see?
