Hello,
I know AIBU but here goes.
Last minute, my nanny sent me a message that she cannot pick up my son because of xyz. I called my ex (DS dad) to see if he was available. Luckily he was.
He picked up DS (9) from school and took him to his after school activity, which I am grateful for, considering it was last minute. However, then ex sent me a message saying that he won't bring back DS till late as he was meeting a friend and decided to take DS with him. I replied to him that DS is going to be really tired and he has to get up at 6.30 tomorrow morning, by the time you come back home, he will be having his dinner really late etc etc.' DS dad said "well I'm already on my way to meet your friend so I'll speak to you soon". He then hanged up.
I'm really pissed off about this. I'm grateful he picked up DS last minute but urrrrrgh I am pissed.
