I have a friend who also owe credit card for $300k before n I have read a newspaper that about some kind of loan arrangement organisation which can help to negotiate with the bank to stop the interest n she took 3 years to pay off the loan n each month need to pay approx$10k but need to have a guarantor. U can try this way to help yr husband n u 2 have no kid which is much easier to handle n cut off some expenses. On the other hand that yr husband said he overdraft the credit card because to pay money for home expenses. May be also need to talk to him that u can live with simple life w/o too much materialistic thing. Glad to hear that u still love yr husband n will stand by him no matter what. Money come n money goes so no need to worry too much. We can solve it finally.
My husband also borrowed money from the bank to start a business but unfortunately it failed n owe money same as u but we also can settle it. Don't worry.
