Exp works during the week and i work weekends so we've always worked that i would have dd during the week and he would have her weekends and for the past 2 years its worked ok. Obviously if one of us needs to change we work it out and so far apart from a couple of times it has worked without issue. Anyway this weekend saturday was my nephews party and it was a last minute thing (they literally booked it and told me about it thursday) i told exp i wanted dd to attend so could he make sure she was there on time started at 2 so not early he said fine and she'd be there. i messaged him the day off an hour before party started and got a message saying they were on their way only for them to not show up and for him to completely ignore phonecalls and messages rest of night so i had to message his sis to make sure dd was ok. this morning at school i asked him where the hell he was and what he was playing at not messaging back for him to complain he only gets so many days a week and apparently 19 hours notice for a party wasnt enought time even tho they hadnt had anything planned that day. so wibu to have been pissed off at him blatantly lying to me about being on his way? he did this 2 year ago at my other nephews party with a weeks notice but apparently im in the wrong because i didnt give enough notice this time
