aar, you are certainly not the only one. my dh is extremely useful though (most of the time). however, it has taken years of - ahem - "training" (read nagging, crying etc ) to get to state of affairs where he can be completely trusted to do most household stuff. there is a downside though, the more confidently he can undertake those kind of things, the more alienated i feel from the household
i still feel a lot of "management" responsibility for ensuring things get done at home or that we make the appropriate life steps, e.g. we have just moved, left to dh, we'd still be renting our one bed flat... another e.g. it took a lot of prodding to get us moving on schools for ds. so i still feel quite a "burden" of household responsibilities.
do men feel the same way? good question. i think not for the reasons sis mentions - it's culturally the norm for them to be the provider/breadwinner and also culturally the norm to work v. long hours to do it - there just isn't the expectation on them to spend time at home in the same way. i also agree that many/most working mothers (based on what i read on mn anyway) take the lion's share of the domestic responsibilities - so they have more to cope with.
sorry that is not much help for your situation, aar. reading your post though, it seems to me that your most urgent issue is not working f/t or not - it is the feeling of having been let down by your partner, feeling trapped etc.
i can only suggest you sit down with him and go through the practicalities v. carefully - when you would like to reduce your hours, when he expects to start making more money from his business and present the figures in black and white. perhaps at least that will suggest a natural time limit on the situation.
another thing i recommend (i did this last autumn/winter when i too was feeling very trapped and miserable in the situation) is to go through all your household expenses and trim them back to the bone - then work out how much (if at all) would you have to work to meet them, taking your dh's contribution into account? i was amazed by what i found! i decided that i didn't want to have to live on so little, so would keep on working - but the big difference was i felt i had made a choice so it didn't feel like being trapped so much any more. i also went through all the advantages of working and thought i would be mad to quit! paid holiday, pensions, health benefits, time away from ds
the other aspect to work on is your resentment of the situation. if you can't sort it out using the practical measures above, i suggest counselling (relate or something) which could help you both resolve your "issues" about the current situation and work out a plan in a non-threatening environment.
good luck
ps - the other think i hate about being the b/winner sometimes is that due to pay inequality, the chances are my family is getting less that if my dh were working in the same field. the average discrepancy in the city is a staggering 40%!!!
