My Sister's $100k Request 🤯

My sister (37F) just stopped talking to me because I refused to cosign a $100k college loan for my nephew (19M). She bought a house recently and couldn't get the loan herself, so she turned to me, the family 'bank' with an 800+ credit score. I said no—$100k is insane, and let's be real, she's terrible with money. I've bailed her out before and got burned every time. She begged, pleaded, promised it was just for one semester, but I stood my ground. Now, I'm blocked on everything, and family birthdays are coming up. Should I be the one to reach out, or just let her cool off? Why does money always turn family into strangers? Would you have done the same, or am I being too harsh? 😤💸 #FamilyDrama #FinancialConflicts #ToughDecisions #RomanticRelationships
