Couple been together for 15 years and 2 kids (3&7) parent one works full time, parent two is a stay at home.
Parent 2 picked up oldest from school (have to walk due to broken down car otherwise both parents do pick up).
About 5 parent 1 said we need to sort tea ( parent 1 usually cooks tea but needed to do a food shop but not had chance). Parent 2 agreed but then carried on with a game with oldest. Parent 1 waiting an hour and youngest was asking to play upstairs with parent 1 being there.
Parent 1 agreed as had washing to put away, then ended up on 2 phone calls. (Step mum and mum about things this week) parent 2 came up and said we need to sort yeah any ideas. Parent 1 said one min just need to do this call, once finished parent 1 text the other to say finished for them to come up and talk. 20 mins later parent 2 came up. Parent 1 asked parent 2 to pick and do the order so parent 1 can finish putting 2 kids and their washing away.
Parent 2 placed the order (asda uber order) and has ordered a bunch of food parent 1 doesn't like (hasn't like this brand for 15 years they have been together).
Parent 1 said they where not hungry which has lead to a massive argument. Parent 2 asked why did parent 1 say we need to sort tea to which parent 1 explained there was still 2 children that needed to be fed even if they where not having food.
Parent 2 then accused parent 1 of setting them up for failure (by asking them to do the order), throwing past stuff in their face (once put food parent 1 didnt like in food and it was noticed and parent 1 wouldn't eat it) and calling them a picky eater (the brand was Asda own pasta sauce but happy with any other pasta sauce just can't it that one). Parent 1 said they expected more from them and after 15 years they should be able to order for the family knowing what each other like just as parent 1 does for parent 2. Parent 2 then shouted that they where not talking to parent 1 again.
Parent 1 and 2 put oldest to bed, youngest had already fallen asleep. Parent 1 waited on the sofa for parent 2 to talk but they refused and walked out. Parent 1 went to bed and text to say they will sleep in another room because of how upset they where over the argument. Parent 1 didnt fall asleep parent 2 went to bed and didnt responded to parent 1.
Parent 1 tried to walk them up to try and talk and turned into another argument.
Who is in the wrong
I believe parent 2 is in the wrong but so is parent 1 for sending the text. But parent 2 wont accept responsibility
