Just had a rather heated debate with my dh, sd has recently started a nursing degree and asked for our support. We agreed to give her some money every month £100. I just discovered that between bursary and wages from part time job she brings home around £700 a month. She lives with her mum so no rent or outgoings other than a brand new car. I think she's taking the piss as she will have more spending money in a month than I do. Aibu?
