Okay ignoring the weirdo who thinks it's weird to have a set eating time with your partner.
Yes, this would piss me off.
Actually, DH and I had a "make or break" conversation the other week and I cited this type of behaviour as one of the reasons I felt so disrespected.
Since then, he either gets home at an expected tone (between say 5.30 and 6) or he at least texts me to let me know.
After All, there are 3 other humans in this house and I also work full time.
This one act has now slipped into other areas - e.g. telling me as soon as he knows he'll be away, instead of the night before, him doing more of the chores at home, without me asking or saying they need doing etc. Etc. It's funny isn't it, once one area of disprect is highlighted, if they truly care, they can suddenly see other areas?
You need to have another conversation, and discuss a plan that works.
(If it helps,DH has a job that is high pressure and he's management, so it can be done if they prioritise right.)
