In May of 2006, I had a good $8,000 racked up by May, 2006. Let's just say that I wasn't too smart about my credit during college; ) I always still paid more than the minimum, and always timely. However, when I got out of college, I paid it all off by May, 2007. Well, ever since May of this year, my credit score has been decreasing! I don't get it! I didn't close the accounts - they are still open. I haven't used the 2 credit cards at all since May, so I don't understand why my score has decreased... Do I have to use the cards to increase my score or something? Help, please
