In addition, if there is no clear financial agreement or economic dispute between you, borrowing money from her may make the situation more complicated.
To sum up, it is not a simple decision to borrow money from an ex-girlfriend. If you are sure that your ex-girlfriend will be willing to help you and there is a clear financial agreement between you, then you can consider borrowing money from her. However, if you are not sure whether your ex-girlfriend is willing to help you, or there is an economic dispute between you, you'd better consider other options.
The best way is to find other channels to borrow money, such as applying for loans from family, friends or financial institutions. No matter which way you choose, you should seriously consider and handle your loan request carefully to ensure that your financial situation is properly solved.
