Whatever happens, do not mix friendship with finances. Venus, your ruling planet, is moving through your 2nd House of Values and squaring quarrelsome Mars today. A loved one who promises to pay back a loan may have good intentions, but could lack the ability to reimburse you. If you're going to assist them, you should give the funds as a gift with no strings attached. However, it's possible you can't afford to part with money that you'll never recoup. If this is the case, turn down their request as politely but firmly as possible.
