In Need of Some Honesty

O k so I just joined this group because I am hoping that sharing with women who have been through similar experiences will help me.... and I definitely need some help right now. Let me start w/ some background information... I've been married to a Marine for two years now and before that we had been together for 4 years. I am a full time student working on my BA in Psychology and I'll be graduating in spring 2010. Which leads me to my point... because I'm in school, I obviously can't just up and follow my husband wherever he goes (even though I would like to) so we spend most of our time apart. Last year he was in Iraq for 7 months and when he came back he was at his home base for about 5 months and we were able to spend a lot more time together because he was only about a 2 hour drive away from my school. After those wonderful months together, we found out he was being deployed again for another 7 months but I was thrilled to find out that he was staying in the state. Sooo now he's working somewhere in the middle of nowhere about 3 1/2 hours aways from home. So you would think I have no reaon to complain right? He can drive home to see me, he's safe and not in danger and he'll be home in months right? Well thats how i felt in the beginning and I was ok with the idea of him leaving. Soon I realized that in some ways this deployment is worse than last year's. Don't get me wrong, I appreciate the fact that I don't have to deal with the fear I faced last year when he was in Iraq but it's still really difficult to deal right now. He works 6 days a week and puts in a ridiculous amount of hours everyday and by the time he gets back to his room he is exhausted (understandably). So most days i either do not hear from him at all or I'm lucky to get 5 minutes of conversation before he's telling me good night. His only day off is Sunday so when he gets off work on Saturday he usually drives out to my house. Then he usually is so tired that he goes to sleep within a few hours and wakes up early Sunday morning and leaves . This has been goin on for about 3 months now and honestly it's driving me crazy! We had more contact than this when he was Iraq and I got actual phone conversations and emails.....now we hardly communicate at all because "he doesn't have time" and even when we are together, it feels like he is a thousand miles away. First I tried to just deal but then I started to realize that my husband has a lot more free time than he led me to believe since he seems to find time to go out to bars and clubs with his friends and spend hours working on his cars on Saturday before he makes it to my house. Aside from that he leaves early in the morning EVERY Sunday even though he has the day off, always claiming that he has things to do. But every time I ask him how he'll be spending his day, he always tells me about a couple things that will NOT take all day. So I try to explain to him that I know he cant spend the entire day with me but it would be nice if he would  at least spent PART of his day off with me. I AM SO LONELY AND MISERABLE and I miss him so much all the time! But at the same time I can't help but be mad at him because I feel like it doesn't have to be this bad. I feel like he doesn't miss me the way that I miss him ....I feel like if he did he wouldn't go days without calling me or be rushing out of my house on Sunday mornings seemingly anxious to get back to the place that he claims to hate so much (it's puzzling right!?) . I keep telling him how I feel and how unhappy I am and I feel like I'm talking to a brick wall because I don't get a response... and nothing changes. Soo heres were I need the honesty, is it unreasonable for me to feel like he's neglecting me? And what should I do? I can't just keep being miserable and depressed but I don't know what I can do...
