If you don't have electric heat or air, the size of the house doesn't matter at all. You need to think about all of the appliances and gadgets you have that are drawing power. It's very common for older couples to have significantly lower electric bills, because they generally don't have as many gadgets and things as younger people, especially people with kids at home. There are exceptions, I know, but the younger you are, the more spoiled you are to things, and all of those things use power. Think about all the things you have in your home, compared to the things your parents have. Most of the stuff uses minimal amounts of power, but added together, it can make a big difference.
The electric company is right about the meter. When they break, they almost always either slow down or quit completely. I work for a utility company here in Texas. I've been there 8 years, and only twice have we had a meter tested and it came back reading high, and each time it was not a significant amount. If I remember correctly, the incorrect meter only caused a 2 or 3 dollar increase in the monthly bill. Your electric company should be able to have it tested, if that's what you want to do, but there's normally a charge to the customer if the meter comes back accurate.
I hope you get it figured out. I know how frustrating it can be.
