Its not the same situation, but my DH works lomg hours, and is rarely home mid week by the time I go to bed. He isnt home from work yet. I work 3 weekdays a week, and on those days, I leave the house early, so he isn't up by the time I leave. We never eat together mid week. If I want to go out in the evenings, or need to work late, and I rarely do, I sort out a babysitter.
In essence, I don't see him, or hardly any of him, on weekdays. He is usually home by 7 or a little bit later, on a Friday night and rarely works weekends.
It is something that I just accept. If I thought about it, I would say that I didn't like it, but we both accept it and get on with it. I find things to do at home in the evenings, keep on top of the housework so that there isn't much to do at weekends, read, watch TV etc. It can get lonely though.
