It depends on what the money was spent on I think.
I have come back from it. My partners business went bust. Unbeknownst to me he had used credit cards to pay wages and bills. When the busiess went, so did his income, so he had to tell me about the credit card debt. He had also 'borrowed' our life savings to prop up the business- although I knew about that. I just didn't know how close we were to losing our savings.
We were in a horrible position. I really thought we would lose our house. It was a limited company, but he was personally liable for the credit cards and company overdraft. He was also unemployed.
The stress I went through was unbelievable. I worry about the lo g term effects that might have had on my body. I would say it was 4 years of hell and poverty (he couldn't get a job, due to his age I think)
It is 7 years ago now, and we have got through it. After 4 years I made him get a job, any job. I couldn't cope with being the breadwinner.
I actually saved some money as well as paying the debts off. We have just used this, as well as using his pension pot, to start a new business in another part of the country. We are leaving the house I fought so hard to keep and srarting a new life!
It has been tough, but I wonder if I would have had the courage to do what I am doing now if I had not been through that awful experience.
