Please help a troubled couple

We are married couple who came 6 years ago to Australia from a very poor Asian country with dreams to improve our life. I completed my study in 2012 and we started to save money for our future. Life was so good as I could see myself having my dreams fulfilled in the future, until 2 weeks ago I found out the gambling addiction of my husband. We had a joint account since beginning and he looked after all the expenses. I assumed all our savings are secured in our bank account. Then, 2 weeks ago I found out my husband lost our all our savings, credit card money and also money burrowed from his father and brother in gambling. We lost approximately $100,000 and we owe $60,000 to his dad, brother and bank. I was shattered. All these years I worked so hard for my future and it’s all disappeared. I don’t know why I had to pay for his mistakes. I would really appreciate if anybody can help me go through this cruelest time of my life. Please!
