Is it so terrible that he had to wait for me?
We currently have one key (just moved in, yes I know we really need spares) and I was just in town with the kids, trying to make my way back with a toddler refusing to walk. DH calls annoyed that I am not home just after 4pm as he wants to go to the gym. He finishes work at 4pm but generally stays a bit later to get stuff done. Anyway, he rarely tells me his plans and seemed to suggest that he shouldn't have to?! He's now gone off, presumably to the gym before picking DD up from nursery but once again I have no idea. I daren't ask 
I'm not sure what I've done wrong other than not communicating about being stuck in town with little ones! I don't feel like I should just sit at home and wait for him to get back either...
AIBU or is he?
