OP I think you need to stop worrying about other peoples marriages and decide whether you can accept your own.
My DH works in the city, is a director, works long hours and is emotionally detached by nature, he is not controlling of me but i suspect he has mild OCD as he definitely likes things just so, he is blunt at times and if i ask him if he likes something or not he will tell me honestly and tact is not a strong point - that being said i rarely ask because i like to look how i want not how he wants me to look. He is not good when I am sick and tried his best when I had DS but it was hard for him to deal with me not just being in control of everything and being fit and well.
I work full time and DS is looked after by a combination of nursery and a nanny, I could stay home but I don't want to and we have a cleaner who comes once a week to help with the housework, shirts got to the dry cleaners for ironing and I tend to take care of the rest - shopping, laundry and so on. He will make me a cuppa - does every night when I crash in front of the telly and he disappears up to his office to work, surf the net, deal with the household stuff
We are intimate in phases - when we are both busy and stressed there are weeks we don't see much of each other, but we make time to watch a movie, go to dinner or have a night out a few times each month
For alot of people the level of detachment in our relationship could be mistaken for a lack of love or care, but it is more that we both require time for ourselves ahead of time a as couple. When dh gets home from work I know he needs some space to clear his head before launching into family life and I give it to him, likewise if he comes in and I am immersed in a movie, he lets me be
Its about deciding if the relationship works for you. If you put it out there on here people will judge you by their own standards and preferences
Your life does not sound so bizarre to me - it sounds like you are disatisfied with aspects of it - but it is in your gift to change it. Speak to your dh about how you feel - when I feel that dh and I are becoming too distant - which happens easily in the hectic schedule we both have I tell him we need to spend some time on our marriage and he responds - he is not the sort of guy who would notice, and i knew that when i married him ..
talk, thats the best advice i can give you, and don't compare your relationship to others
