In October last year I told my ex boyfriend hold on to my credit card so I wont use it. It so happened that he used 1200 dollars on my card and now I am in debt. HE would sometimes make the payments off n on and I would have to because its under my name. My credit is really bad now because he is either pays it late or he doesnt pay it at all. Now he hasnt paid the bill in 2 months and I have been makin the payments. I want to sue him for my money. I made him sign a written statement but I moved and I cant find it. All I have is the transactions he made on my card statements and my brother as a witness stating that he would pay it. However, thats all I have and messages stating that he would pay it. Is all this information enough to sue him? I need some advice on what to do.
