I have a just 17 year old (half)sister who lives with my mother, stepfather and other assorted siblings and half siblings (mother been married 3 times). I am 23, married with my own DC and live 300 miles away.
Over the years I have been a bit concerned over how my sister has been treated by our mother. She has been bullied to be blunt. My mother is also physically abusive on occasion as she has been to all of us.
My mother and stepdad have planned a holiday Florida over this Christmas period (including Disneyworld) and I have found out from another sister this morning, that my younger sister is not going, will have to stay with my stepfather's parents while the others are away and has been told by my mother that she is not to enter 'their' home until they all come back.
My mum had told my sister back in June that she had to save money from her part time waitressing job to cover the costs of her hotel room, food and spending money as they would not be paying for her, just her flight, and as she had not saved enough and after a row said she did not want to go anyway, my mum has now changed the name on her plane ticket to that of my brother's girlfriend so she goes with them instead.
Out of the other siblings that are going (the ones who still live at home) two have full time jobs and the other two are primary school age. My mum has not asked for money from the two that working full time
.
I have rung my mum and had a go at her as I think it's really unfair but my mum insists that it's her 'own fault' for mouthing off that she didn't want to go. I know she really did. None of us have ever been abroad due to finances and it will be their first trip abroad.
I have said that my sister can stay with me for Christmas as my step-grandparents are bloody nightmares tbh and there won't be anybody else there but my mum has said that she can't as she has to work.
AIBU to think that my mum is an utter bitch?
