I think my DW would have made the same post a few years ago - she may still do now to one extent or another (although I hope not).
We got into a similar rut - I was working very long days out of town and away on a fairly frequent basis.
She works too - closer to FT than PT - but was left with most of the household chores etc.
I would get back from work after the kids had gone to bed and not long before she had to go as well. We had different schedules and most of our conversations would be 'practical' rather than 'enjoyable'.
We saw things differently. We would have rows about how much she was left doing at home.
I offered to pay for a cleaner - "that's not the point"
I would do a good amount at the weekend - "I should hope so"
I would ask her to leave things for me to do when I got back as "I can't do something if I'm not here" - "Exactly! But if I leave it I can't bear to sit and look at it undone"
I would drive to work and back home each day, covering a distance that some would see as far enough to book a hotel and stay over - "Well thank you Mr husband and father of the year!"
I earned very good money and what we could do and buy increased significantly - "So!"
Sex could be perfunctory - I'd hope she would not say she was always going through the motions though - and I would (occasionally) sulk (for a short while) if I was rejected. We too had occasions where we would stop because she was not into it and I was getting pity/duty sex (a massive turn off for me and, I would guess, most men).
Has it changed since then? Yes definitely. I like to think we are happier than we have been in most of our 20 yr marriage, and definitely happiest since the kids arrived.
I have another business I am concentrating on closer to home - although the other one will take me away for parts of the year (I have stepped back from it but need the income it provides so cannot leave it entirely)
I cannot remember what the trigger was for me. It was not a conversation or a row, but I do remember being sat in the office and thinking to myself that I was not happy, nor was she and we both probably felt unappreciated in one way or another.
I remember thinking that, from a financial and practical point of view, divorce would be easy and maybe we would both be happier with that.
Then I realised it was not what I wanted and the thought it may be what she wanted was very painful. I knew I had to do something (also thought of the question James Gandolfini asks Julia Roberts in The Mexican)
I remembered the cliche that men need sex to feel loved and women need to feel loved to have sex and decided to do what I could on that side.
One night I told my wife I missed my girlfriend - not the best choice of words for what I meant tbh and I can laugh about it now.
I told her I missed the days when we had time for eachother and it was just about us two. I wanted to start taking her out as my girlfriend and not my wife. Proper dates with the aim of being alone, talking and holding hands etc.
I wanted her to want me physically - what did I need to do? I could not change my hours at work, but I could explain my longer term plan. That I did not like travelling and being away so much. That I did not really like the hours or the work but that I planned to get myself to the position where I would be home more in a timescale I could give her.
I found out that part of it was she was worried about my health and the money was not a good trade off for her (that was a shock tbh as my health never concerned me).
We both agreed to try to understand the other more - reality was there was not much about our life we could actually change.
The only thing we could change was how we treated each other. I tried harder at home. She tried to agree to come on dates with me (when the family diary allowed).
We have v sporty kids so our weekend tends to start at 3pm on a Sunday when all the sport is done. Staying out late on a Friday or Saturday is not appealing when you have to be up early for kids sport the next day.
We both slipped at times but at others we were experts on the early bird menus of local restaurants.
It worked though. That 'just us' time made a difference. It even extended to the nights we were at home when we would be working together to get the kids sorted so we could sit on the sofa together (even if we were doing different things) rather than in different rooms, barely talking before we went to bed.
It takes effort from both, and an understanding that you will not always agree on what can and cannot change.
Sorry the post is so long but I hope it helps
