He works evenings so Mon to Friday most days he isn't here with the kids. I have 5 and it's bloody loud and hectic and I'm struggling lately with my mental health and some other issues (lapse in an Ed).
His mum runs a business and got a job with a mutual friend.
DH won't get up this morning till 10.30 am.
And when he does he announces he's going to help his mum today 
I'm annoyed because
A. I'm always dealing with the kids alone. It's raining, I have no money. I was going to do a food shop today and now can't (don't drive and can't get 6 of us in a taxi) The kids are bored and fighting.
B. He didn't even tell me he was going till 10 mins before he left.
C. It's his mums business. It's not his responsibility. If she can't do the job why is she taking it on?
AIBU to be fucking fed with this.
