Marriage....Is it really worth all the crap???

So, I got up this morning angry again. I have been married to my husband for almost 4 years, and I am begining to wonder if it is really worth the fight anymore. I feel like I am standing in the back of the line just waiting for him to put me at the head of the line. I am married to one of the most selfish men I have ever known, and let me tell you It really sucks!!! If I need something I have to wait. I am not gonna get it twisted by thinking that I should come first cause in this life that I live I will always come in second to his Job. ( he is in the army and that is his first priority) I think it is bullshit if you ask me. Regardless of what his job is he should want me to be first. It is how things work right?? Or am I jsut wishing for something that is just out of reach? I am tired of not being a top priority in his life. I have done everything I know aside of screaming in his face to get him to see how I am hurting and he still won't listen. I need to be the one that he can't live without, the one that he would go through hoops for. I don't know what to do anymore. Maybe I would be better off alone without him than alone with him....
