Again.
My mums... um, how should i put it, pretty unlucky with money.
She's had to move a lot and we were homeless a few times as kids. Living in b&bs/caravans etc. Most of the money and house from my parents divorce went on posh holidays (6 weeks here 5 weeks there etc etc) in posh hotels and my 'D'F wasn't about.
Just a bit of background.
She does work hard and i realise that its up to her what she spends her money on.
But...
She's still renting places that she can't afford to rent so everytime gets kicked out and has to move.
I am TBH so fucking fed up of bailing her out, giving her money, helping her move, sorting out the bailiffs at the door. I have my own very young family to look after and she does sod all for me..... Oh actually i had a 2 day late birthday card for a big birthday couple years ago and she did baby-sit last month, when the kids were in bed tho 
So today she's moving again and my Dsis and DBro are helping her - for the first time!
Aibu telling them that I'm not helping? Am i being a bitch? I've already told them BTW. They weren't impressed.
