A couple years ago my fiancÚ let me fix her financial mess. She had credit card debt, multiple loans. I calculated she could save over 3,000$ in interest by paying it off. My intention was to pay her debt and instead of paying credit companies she would make interest free payments to me. I paid her debt without her knowledge. Shortly after paying her debt she stopped allowing me to manage her finances and refuses to pay me back. Is there anything I can do legally to get my money back?
