Help! I'm missing my husband.?

This is my 2nd marriage and we will celebrate 2 years soon. Neither of us are spring chickens. We are both in our 50's. He will retire in 3 1/2 years and due to his age and the economy, every day he worries about the possibility of being let go and losing his retirement he's worked so hard for and for which we have been looking forward to. When his company says "jump!" he asks "how high?" He leaves for work early and comes home late. He often has to drive 3 hrs to work and back several times a week. When he returns home he has several hours of work to complete on the computer. After he eats, he goes to bed around 7:30 nightly. On the weekends, when he's not sleeping, he goes to breakfast with his buddies or to play poker. I told him that for the past several months I have been very unhappy and depressed because of it. He said, " I know and I'll try to be a better husband." I told him he already is a good husband but I need some of his time and attention. I also told him that rather than feeling like his wife I feel like a room mate or a boarder who works for her stay by caring for the home etc. This morning he was working in his office and after a few hours he said, "I've tried to do what I could here at home but I can't finish what I need to finish without going to the plant. So, he showered, dressed, kissed me goodbye, and is now on the road for another 3 hour drive to work. He said he'd see me around 7:30 tonight. I'm crushed right now. I'm so lonely! I totally understand the pressure he's under and I try to keep up my end of the marriage by keeping a clean home, laundry done, bills paid, dinner ready when he arrives home, but then when he does, he only has a few minutes of conversation with me and then it's off to bed he goes. I feel like he's avoiding me and it really hurts. If anyone has ever been in a similar situation, could you offer me some advice? I feel I'm on shaky ground here and am concerned for our marriage.
