So,I got a problem.
I'm 18 years old(turning 19 in early June) and I'm engaged to the best girl in the world,She loves mud and loves both my trucks.Were planning on getting married in August of 2009.

There's only one problem.

She lives about 54 miles north of my house and I end up going up there at least every weekend and feed the old gas hog most of my check through out the weekend and week.Also she doesn't have a vehicle to drive.I don't only feed my paycheck to that but it does take quite a bit.
My main problem is that I want to finish my other truck.I don't want her to get upset with me.She understands that I want to do that but she loves being with me most weekends.Which means money is spent on gas.

I want to be able to see her,but I also want to get my truck done.What should I do?I don't want to make it seem like my truck is more important to me than she is because it's not.But it is pretty important to me.So,what should I do?

Thanks.
