DH works an early shift, starting at 5:30. So he is usually leaving about 4:45, he has a bit of a commute. He picks our primary aged children up from school on the way home, but as soon as he gets home, he showers, eats a lunch type meal and goes to bed. Wakes up around midnight and repeat. Once he wakes up, he will do a wash load, give the kitchen a wipe over/clean up the stuff from the kids dinner and just general house things, including make the lunches for the youngest ones and have their uniform out, etc. but he is not seeing the children at all, apart from the small period of picking them up. We have 2 in primary school (7 and 9) and a 14 year old. 14 yo is barely seeing his dad at all, as he comes home by school bus and if he has an after school club, he won't see his dad for the whole day.
So many of my friends tell me I'm lucky he helps around the house, etc. but I really don't think it's that lucky when he isn't actually in their life at all, he could have the whole afternoon and evening with them, spending time, getting an early night, but he just doesn't.
