Hi there Katy,
I was in the same situation 10 years ago. My ex-husband got us into �30,000 of debt due to drinking, gambling and over spending. Ex-husband would never discuss money, but loved spending it! Eventually we split up and I had a terrible time not knowing what the future held.
I went to the Citizens Advice Bureau and they were fantastic. Helped me contact the creditors etc, and was able to get my life on track without my husband. Infact although he was the bread winner, I actually was better off financially, as I was able to save money, eventually paid of my debts over 5 years. I eventually built my own business, and have now found a wonderful partner and haven't looked back since. Financially I am confortable now, something I would have never believed! So chin up hun, there is light at the end of the tunnel...it just seems along way away. Hope everything goes the same for you. My advice would contact CAB and a solictior, so you won't go through this alone! Best of Luck xx
