I'm a single mum with an 18 & 21 YO both working FT. Youngest is not pulling her weight and keeps telling me she can't afford to pay me keep this month. My eldest pays me on time every month. I'm struggling to stay afloat and rely on their contributions each month. I've currently got the house on the market (following divorce) and struggling to see how I'll be able to afford a house that will have three good size bedrooms for us all. I'm thinking my DD is going to have to downsize to the box room as she is not paying her way. She takes all the time but never gives, I'm fed up of being a doormat. AIBU?
