We've been apart 4 years and the dc spend 3 nights per fortnight with him. Until now I have filled in all parents' evening forms, liaising with ex about which times he can do. Last year he forgot the date after I'd told him the time we'd got and didn't attend, then sent me a shitty message because I should have reminded him apparently. Another time he didn't reply when I texted him the time we had been assigned so I wasn't sure whether he was coming. On the night the teacher was ready slightly early so asked if we could start. I said yes and then he stomped in a few minutes later muttering he 'had been told X time,' and glaring at me, which was embarrassing.
He thinks it's clever to seldom reply to my texts, which can be infuriating, and causes problems when arranging pick ups for the dc. I sometimes have to ask the dc to confirm stuff with him and let me know, which I don't think is fair to them. Last week he failed to reply to my text asking him to confirm he was picking up the dc from school on a different day from usual, causing me to ring around 3 different people trying to sort something else, and then come home from work early myself only for him to be standing smugly in the playground smirking when I got there. I had to drive straight back to work (had an evening event) and it wasted 1.5 hours of my precious time and petrol. I work fulltime in a very stressful job and he does the bare minimum for the dc and pays nothing towards their upkeep, btw.
AIBU to think he has the same access to the school website as me and is aware that parents' evening is a thing, and not to contact him about it? He probably won't reply anyway, which will stress me out and I'm not his fucking PA. The only thing is ds2's letter was in his bag and I know ex didn't see it. However, we've been attending a pre-halfterm parents' evening at this school for the last 6 years, and he is just as capable as me as remembering this and contacting the school or texting me and asking about it. If he texted me about it I would be happy to tell him the appointment time I've got, but I'll faint if he does.
AIBU?
