What happened????

My mom took my daughter for the evening, so I could get some work done. As soon as she pulled out of the driveway, I had tears come to my eyes. I felt like my whole life just left... first my husband and now my baby. I know it's a good thing for my daughter to spend time away from me. It's good for both of us. I just reacted in an unexpected emotional way. I took a nice, long bath and read a parenting magazine, then made dinner and worked for awhile. But just a few minutes after my daughter left, my husband called me. He called me yesterday to tell me he was leaving the country and where he would be going. Then called me today to tell me where he is. It's hard to believe he will be gone for such a long time without seeing us at all. He was deployed for a year to Ft. Leonard Wood, but we were close enough we saw each other almost every weekend. He was been to Benning and Huachuca too for several months each time. But each time he flew home and/or I flew there to see him to break up the time. This is the longest he will be away without coming home and the first time in our 10 year marriage that we will not be together for Christmas. I hear our daughter every time she hears anything that remotely sounds like a door opening saying "Daddy's here?" and it breaks my heart. I have to tell her "No, daddy's not here. He won't be home for a long time." Tonight she pointed to our large wedding portrait and said,"I see Daddy." So I took her to the picture and she said, "I touch it." Even though her daddy has been gone many times before and for longer periods of time, she already must sense this is way different. She wears her little pin proudly proclaiming "A piece of my heart is in Afghanistan" and doesn't want to take it off. We also have a bowl of m&ms next to her fish. Every morning she feeds her fish and eats 1 m&m. When the m&ms are gone, daddy will be home. I don't think I will ever get used to this.
