Thankfully I never bought into the whole credit card scam or the credit scam in general. I never understood the idea of paying more for something by using a credit card with the fees, interest and all of that.
My ex on the other hand maxed out every card he got - and the real horror is I worked like a dog to pay off those cards for him and he maxed them out again.... no that isn't the real horror - to my shame I paid them off TWICE and he maxed them out again.
I just didn't learn the first time. Love is blind and apparently stupid too.
