Duped Spouse

I married a greek immigrant in 2002...he received his permanent resident card...we separated Jan 2006...he fled the country...left me with his debt....he owes credit card debt which thankfully i am not responsible for....he forged my name on transfer papers so he could sell his truck which I was co-owner of....I think he should have some reprecussion for this....can I go after him for the debt....or at least have him not be allowed to enter the country??? What can I do....I will be getting a divorce some day soon....what happens to the clause "I am responsible for him for 10 years"??? Please help or direct me to someone who can help me. His name is Grigorios Pavlaki Apostolidis....

Sincerely,
Rene Q
