My DH works long hours and has to do some client entertainment after work. Because he has a commute and then a drive from station he sometimes (more increasingly) stays over in town. He also travels a lot for about a week at a time. This AIBU is not about that, although I have my issues with this too.
When my DH is away or when he is away all day/ night he doesn't get in contact with us. So, for example yesterday he left for work at 0630 and I haven't heard from him since. I don't expect him to call me up when he is busy at work but there are lots of gaps in his day e.g. commute office to hotel he is staying in etc. I am not checking up on him. We have 2 DC and I just think it is off that he doesn't even call up to see if they are alright or what are we doing. I sent him a message last night and he read it at 0130 so he was out till at least then.
I may not hear from him till he walks through the door later tonight. Whatever that time is. Sometimes I look on my phone tracker just to make sure HE is OK because I haven't heard from him. If the tracker moves around during a few hours then I know he is still alive.
He thinks I am BU when I have pulled him up on this. I've also told him I am not happy about his travel, client nights out and stay overs and was told that when I work in the city I went out all the time. Well, yes but that was in my 20's when I had no DC. My point to him is that he is a married man with youngish DC and acts like he is single at work.
