Hi
Firstly, just to let you know I am a debt adviser, and there are lots of options out there for dealing with credit debts, so don't panic! Please seek advice from a charity offering free debt advice, like your local advice centre, citizen's advice bureau, or CCCS, who offer advice over the phone. Don't be tempted by one of these shady companies advertising on the internet or daytime TV that claim they can wipe all of your debt; they will charge you a fortune and may not advise you correctly because they are in it to make money themselves.
Unfortunately, there are not many remedies available that would not involve drawing up a financial statement to get an idea of available income to pay off the debt, or to identify if indeed you do not have any income with which to pay off the debt, and as you are sharing your home with your partner they would need to take the income he brings into the household into account.
Unless you have no available income left over at the end of the month as a family with which to address debts (this is after you have spent on all your essentials), they would expect a payment based on what is left over, i.e. you would have to ask your husband for it. Also, any good money adviser would want to know what other debts you have and what is happening with these to get a full picture of your situation.
Without wanting to go into too much detail here, do not panic, as nothing terrible will happen to you because of a credit card debt.
I am more concerned as you say you have other debts as a couple. Is anyhting being done to address these? Maybe you should suggest to your DH that you seek debt advice as a couple anyway?
Secondly, IMHO, and I hope you don't mind me getting more personal, it sounds like you are scared of your DH... does he really have the right to go so nuts if he finds out you've run up a credit card debt? I presume he is at least partly responsible for the other debts in your household?
From the language you use it sounds like your self-esteem has been knocked. You are not stupid or childish for running up a debt, it happens to loads of people, but it does need to be dealt with rather than hiding it, you will feel so much better once you have faced up to it. If you do not feel strong enough to tell your DH yet get some general advice on your own, but in the long term, I would be concerned that if I was really so scared of my partner's reaction to a credit card debt am I with the right person?
