For background; I’ve always had a difficult relationship with my sister. She’s very selfish and thinks the world revolves around her. My mum is very similar, she has issues respecting people’s boundaries and thinks everyone should do what she wants.
Myself and my partner were made aware a month ago that my sister was moving house at some point this month, and it was looking like it was around the time we were going on holiday and moving house ourselves. My mum had asked us if we would help her move I said potentially.
Fast forward a week, and I find out my parents are taking my sister and her daughter on holiday for my mums last ever abroad holiday. We were not asked and again my little boy misses out. A few more weeks later my mum rings me and talking about other stuff and then informs me that my sister got engaged the week before but hasn’t told me. I know we aren’t close but I am hurt that my own sister didn’t think to ring me up to tell me her happy news. I told my mum this and she brushed over it and I asked me if I would help my sister move house in a few weeks time. I said no, if she can’t be bothered to tell me about her engagement why would I go out of my way to help her? My mums response was it wasn’t my sister asking it was my mum. I said it doesn’t matter it’s still helping my sister out. My mum left it at that because they were going on holiday and I knew she wouldn’t want to argue before they left, but I’m sure when they are back this week it will start again.
This is the week they have all gone on holiday and normally if my parents are away I hear off them a couple of times, but this time nothing at all.
AIBU for not wanting to give up my weekend to help my sister move house?
