Any Biblical scripture to help with the following problem?

---My problem---

My Ex-wife (been Divorced for 20 years). 1 child with her. I was out of the country in the Navy a few years back. During that time, she created a loan in my name, received the money and never had the slightest desire to tell me. She is a Police Officer. She is my kids mom. What am I to do. If I make a complaint as to the loan, then she could get in trouble and lose her job. She is after all still my kids mom. But, now I have this obligation to the tune of $32,000. Over time I guess I could pay it, but I really do not think it is right. I don't want to pay it, but I am not a person to just do something out of animosity. I went to Lexus to obtain a car today, and all of a sudden this is showing on my credit---they still sold me the car, but man o' man was the joy diminished.
