My mother was a recovering alcoholic with many months of sobriety under her belt and was doing brilliantly. I trusted that those days were behind her. She was never a "wake up and drink every day" type of alcoholic, but a binge drinker.
I was offered a little part time cleaning job that conflicts with my OH's job so he wouldn't be able to have the children, my mother was insistent I take it. It's only 8 hours a week.
"it will be good for you to have some time away from the children, it'll be good for your mental health, go on - do it. I'd love to spend more time with the children. I'll have them. Please, do it. Think how lovely that little bit of extra money will be at christmas"
So I reluctantly took the job and even started to get excited about it.
Week 1 all goes great, the children are happy that grandma comes to sit with them at my place for 4 hours 2 days a week.
Week 2 she's decided to start drinking again, after months of being dry. She turned her phone off and left me in the lurch. Not so much as a phone call to tell me she isn't coming and has screwed me over with work.
What I want to know is was I unreasonable to trust her in the first place? I'm upset, at both her for doing this to us and myself for being such a fucking idiot.
To add: she has never drank around my children and wouldn't. I would never leave them in the care of somebody who is drunk or drinking.
YABU - you shouldn't have trusted her in the first place
YANBU - she has let you down, she's in the wrong.
