I genuinely don't know who is being unreasonable here.
We have two daughters together, one school aged and one 11 months old. We have been seperated for 6 months and generally get on okay.
Yesterday I took DD1 to school, got back to the car and it wouldn't turn on. The baby was screaming as it was her normal nap/feed time and I was getting really stressed. Ex would normally be at work so I called my DF who jump started me to the garage.
Ex messaged at around 11 to ask how the DC were and I replied and told him car was now in the garage etc. and he knew that I would now struggle to get DD1 from school as we live a driving distance to school. I got two buses to collect her at the end of the dday and thought no more of it.
At the end of the day ex text again and he only then mentioned that he had the day off (unemployed/cancellations). And I am really upset, he knew my car had broken down so he could have easily helped out picking up DD1 or look after DD2 so I didn't have to drag her out in the cold (she has been poorly).
He said as it wasn't his day with the DC IABU but I think given they are his DC too he could have helped out?! He wasn't 'busy' and was just at home.
