Mooycow, you need to sort this out now before it becomes critical.
Firstly, talk to your husband, get it all out in the open frankly. Then make a repayment budget and cut the debt as soon as you can.
A good place to start is on the Martin Lewis 'Moneyfacts' website. Find the 'Debtfree Wannabe' forum thread and get some help from the other debtors. They are brilliant: supportive and full of good advice. The first thing they will ask for is an SOA (a statement of accounts) where you post your income, outgoings and liabilities. They'll then suggest where you can make savings.
At this point you might want to Google You Need A Budget UK which is a paid for website which helps you manage debt. It comes highly recommended and you get a free first month.
The next thing you should do is make a list of your debts to various cards in the order of the highest interest to the lowest. Try to get a long term 0% interest card to transfer your worst debt to and, use the money you would have paid in interest to pay back the capital. When that's cleared move to the next highest credit card debt balance. On no account take out any more credit or run up any more debt.
The Martin's Moneyfacts website warns against too many card applications damaging your credit limit but they have a 'Soft Search' facility where you can enter your details and it will give you a percentage chance of getting any card without it being seen by Experian or any other credit file company.
Cut up all your credit cards so you cannot use them again. Martin's Moneyfacts people advise keeping one credit card only for dire emergencies and to freeze it in a pint of water so you can't get at it quickly and have to think about using it.
Good luck. Once you are out of debt you can then use that money to start saving instead.
