I have a strained relationship with my mum. She's on her own and has this expectation that me and my sister will 'entertain' her every weekend. My sister indulges this, whilst I try not to.
My question is regarding when we go out for lunches/dinners. She expects me to pay. Every single time. Never puts her hand in her pocket or even offers to split the bill. I'm starting to resent this and it's putting me off from arranging to do things with her. She's not skint, and nor am I. I can usually afford to pay. But is this normal - is there an expectation that adult children pay for their parents all the time? AIBU in expecting her to offer to pay once in a while?
