Be strong and hang in there!
I'm married to a trucker (or in his words, "not a truck driver, but a car hauler"), to me, they're all the same. We've been married for 32 years, parents of 2, grandparents of 3. Out of those 32 years, you could say me and my husband have spent probably a total of 4 years together, the rest him being on the road.
Other then him bringing home the money, which I can say has been very little, for all of the time he's been gone, I've had to raise my 2 kids and all that goes along with that and maintaining our home. By the time he comes home, maybe every other weekend, he's so out of the loop and distant from us, that it's like he's not even there.
He's too tired to do anything around the house, he doesn't want to go out to dinner, because he's eaten in restaurants all week long (how nice for him) and forget doing anything else fun. You might think how stupid of me to stay in a marriage like this, but after a while you kinda get numb to it and it becomes a habit, one not easy to break.
My kids are grown with their own kids now, and lucky for me they are all around where I am, so my life is full. Just wish the man I married was here to enjoy the kids and grandkids, too. He's the one missing out on it all. So, to all of you wives who are married to a trucker, be sure you are strong and can handle a lot of time alone, it's going to be a long road ahead.
