My parents divorced when I was a child. My mum's emotional health and financial position have been poor since. She's a lovely person but can also be manipulative at times. She did not handle divorce well and was not 'strong' or protective of her children's mental wellbeing (we knew all the gory details of dad's affairs etc). Example, she'd make me feel bad if I went out on NY Eve with friends and she was home alone. Didn't ask me not to go but gave the sad eyes and forlorn expression. So nothing big or abusive, but emotionally manipulative (I believe, anyway) and just given here as an example for context that the issues, as such, were small but always present.
I felt that at some point in my teen years our roles switched and I almost became the parent to her, even now I don't tell her any of my problems/worries. In the absence of a partner, rather than crack on with things, she's always asking my sibling and I to do things for her e.g looking after her dog if she's out for the day, driving her to hospital appointments, helping pack the house up when she moved last year etc. I would like to know if I am being unreasonable for resenting this and if I can/should say no sometimes. Or is this normal and what kids should do for parents? She's mid-60s BTW so not particularly elderly. I work and have my own young kids and two dogs, yet at the moment the expectation is I should drive to her house once or twice a week to walk her dog and take her car out for a run around as she's injured her knee. I barely have time to walk my own dogs and I hate driving her car! I told her this was too much, to be greeted with a sad face and a list of reasons as to why it's easy for me to do these things.
I don't know if I am right to feel resentful or if my upbringing has just given me an intolerance of 'weakness', as I see it, and I am being mean to be fed up with it. I know if I were in her position I would just pay a dog walker for some walks and accept the dog won't be exercised as much over the coming weeks, then get back to it when my knee was better.
