I just found out my sister has been paying £50 a month for tv for the last few years, all the while claiming poverty so she cannot pay for her own coffee if we are out (when she is not claiming she has forgotten her purse) or offer any money for petrol when requesting lifts. Obviously its her money but I feel so taken advantage of when I have effectively been subbing her for a few years while I have been struggling. She smokes and buys convenience foods, and keeps equipment for an expensive hobby so she has lots of places she could cut back, but I have always been able to justify those things. I know this is just the payment for her tv, she let it slip accidentally when we were talking about something else and then kind of caught herself. I feel totally taken advantage of - AIBU?
