How Do You Say Goodbye After Just Saying Hello?

Dearest Prim,
How do I explain to you that daddy is leaving soon? What do I say to help you understand that it won't be forever but at times it may seem like it. In just a few weeks daddy will leave for Iraq. After only saying our first hello seventeen months ago we will have to say goodbye. You've had so many goodbyes-too many for such a little girl. How will you handle another disruption....someone else who leaves your life unexpectedly. My heart aches for you and your brother. It took such a long time to finally give your heart to this man who replaced one that you had already loved as your own. Now he leaves and every morning when you ask me where daddy is-just like you always do-I will have to explain all over again that daddy is at work and won't be coming home for a while.
My precious babies I hope you will understand that our sacrifice allows daddy to serve our country. That we are all a part of something bigger than ourselves and that our strength will come from God and our love for each other. We love you so very much. We know that this will be difficult but we also know that God will not give us what we can't handle. One day I hope you see that distance can never separate love and that joy can be found in sadness. We are a family forever.

Romans 8:38-9 For I am convinced that neither death nor life, neither angels nor demons,[m] neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.
