I'm very close to my mum and I love her but my sister finds her annoying (she has anxiety and is quite annoying tbf). She spends my two days off with me and my daughter each week which can be a bit much but she adores her so I do it.
But when my daughter goes to school she keeps dropping hints about us having a girls day one of my days off. I'll be changing my working hours so I'll have to work for part of both my days off, as well as walk the dog, fit in all the housework, washing, cooking etc during school hours as hubby is a teacher and works long hours during term time.
I also kind of want to go to an exercise class or do something else for myself having had four years of zero me time. AIBU to say no thanks, I'm busy.
My sister gets frustrated with her as she's retired and has no commitments at all whereas we both have jobs kids and dogs so don't have the spare time she does.
She also doesn't want to spend all her spare time with my step dad which I get, but rarely has my daughter of a weekend so my husband and I also never get any free time, it always has to be when I'm there so we pay £70 for nursery every few months to get a rare day together. She's also very ocd about housework and will obsess about my house when she comes over under the guise of helping but which makes me feel inadequate and a bit ocd myself, I have told her about this but she still doesn't seem to get it!
