DH is a teacher and can leave work quite late, I totally understand this, teachers put in a lot of extra work and I can also leave later than I should, that isn't my AIBU. However the main difference is DH never tells me he'll be late but I will always let DH know before or when I start to run late. Although DD has childcare arrangements this does affect our evening as her childcare is near his work, if he were to text me I could make sure I left work bang on time or a slight bit earlier if necessary to pick up DD so she could have a consistent routine. If I am at home, I sometimes wait for us to have dinner with him but then have to call him to be told he hasn't left yet. In the last week he's been consistently late without a word from him.
I'm probably going to have to be leaving work myself on the dot to get her instead from now on but AIBU to think even as a teacher you are able to send a quick text to say when you'll be leaving or that you'll be later than usual?
