Emotions run a muck

"Things are never what they seem." You hear that a lot growing up and it isnt until you are a bit older and wiser that you realize that it is true. You are somewhat jaded by that time and even though you are past your past you carry with you emotional baggage that no matter how lite or how well you have managed it through the years, seems to always get heavy at the wrong times.
My husband is deploying here in what seems to be a short few days. In reality it is 16 days, but short and few all the same. I am going through these stages of deployment that I keep hearing about and even though I am now in the withdrawal phase for certain, I am also going through this uncertainty. Not about myself or even about him in general. About us. I fear that he will be over there for a year with out me and men have their needs just as everyone else does. What will he do? Or the better question is who? I go back to the three week training he had when I was pregnant and our FRG leader who specializes in starting trouble emailed me a picture of my husband on top of a female soldier. They were doing training and there were many around them in that same position so I know that thinking something would be stupid. At the time I didnt even give it a second thought. I trust my husband, and I know better and I am not one of those types of women that flinch every time a woman is near my husband.
BUT NOW. Now I am feeling protective and jealous and I cant understand what s going on with me. The same soldier in the picture with my husband is now the center of my worries. She is married too and I have spoken to her once, I even told her about the picture thing and what the FRG leader had done. She seemed just as taken back by the situation and told me she barely knows my husband. Big unit, its possible. But every thing is getting to me now and I worry about what will happen when everyone is on their side of the world for the next year. They will be working together on the other side, away from spouses and with the same needs that they have now. What do you do if y our spouse cheats while they are over seas with the military?
If a spouse does it over here it is like the world has ended. They should be exiled and stripped of any spousal priveledges and friends. Even I have been drawn into those feeling of "Oh my God, how could someone be so heartless and dishonorable to their spouse who is serving." But what if it's the soldier? What is the protocal for that? What feelings are we supose to have for that situation? And what do I do if that soldier is mine?
I love my husband with everything that is me. I trust him. I know how he feels about cheating. He wanted to kick his father out of our lives and that of our childrens when he found out he cheated on his mother. He is strongly opinionated when it comes to that. But a year is a long time. And I know how it is to work closely with someone and when you are there and away from your spouse for a year, it could be easy to forget that you are married.
Maybe this will pass as the other stages go on by. Maybe I will never have to deal with such things. I guess only time will tell.
