I have been living with my girlfriend for a few months and have decided to go our separate ways. Unfortunately in this time I have credit card debt from paying for our car insurance, an engagement ring, and a new vehicle so that she could use my car since she wrecked her own. The total amount of debt is anywhere between 3,000 and 5,000. Do I have a case to sue for debt repayment, and if so how do I go about this in the best/most efficient manner?
