Argument with DH

[GreenLightMoment]

First serious incident/argument in years and years. I have name changed for this.
Might be long but hang in there.
My sister in law on DHs side is always asking for favours, taking her kids to school, picking them up, taking her shopping to the super market etc (she doesn't drive), and upto now I'm 35 weeks pregnant, she hasn't once offered to help out with my DS, picking up from school or anything. She starts work earlier than us, her DH is currently unwell so he can't do much but not that he helped out much before hand anyways.
So every Thursday me or DH will get a text asking if we can pick up her child and take him to school as him and our DS are at the same school. Now me and DH both work so going out of our way at 8am can be annoying.
So I said to DH tonight, are you taking ? To school and he said yea I've been asked and i will take him so then me being me I said I'm sick of being asked for favours when no one offers to help us out. He got defensive as its his side of the family and threw his food on the floor and stormed out. And I don't know where he has gone, he has never stormed out in the past.
WIBU?? Fair enough if I was and I just need perspective on the situation.

Do you ever ask for help? They ask for help and get ut. If you don't ask you don't get.

Yanbu fkr.leaving the food though.

Have you asked for help from them? People will not know that you need help if you don’t ask!

Your husband was being childish

I guess the solution to this is that if they ask for favours, he's always the one to do it, not you; since he doesn't mind and you do.
Throwing food on the floor solely based on what you have written is a very bizarre reaction from an adult.

Have you asked for favours? If not, try it! Now sounds the ideal time.

Also I'd say calmly to your DH that he is welcome to help his SIL out as much as he pleases but as your very pregnant you'll be taking a break from it.

your SIL sounds like a total pain in the ARSE
