Deployment/relationship related...?

My boyfriend and I met on deployment to Iraq a few years ago and fell in love. He went home a few months before I did, but we promised to live together when I got back. So I moved to a new state and went to a new school to be with him. I even transfered to the National Guard in his state from the Reserves(which is not an easy process for those of you who don't know). We lived together for about 2 and a half years. Our relationship wasn't always easy, but we always loved each other and we were each others best friends. He found out a few months ago that he would be deployed again...his mission this time may be more dangerous than it was for him last time. He is an MP and right now he is training to be a turret gunner for convoys...when I met him in Iraq he was basically working a desk job as intelligence...but I think somethings he saw the first time he was over there freaked him out. He had to go through a dead soldier's personal items(he didn't know the soldier)
