I think your husband loves you very very much, but he just does'nt understand your sorrows completetly, i've seen it many times, a person thinks just because he/she works that the person that does'nt get paid for working in the home, keeping it clean, taking care of the kids, taking out the trash, or taking care of a parent, that they do'nt work just as hard and they have it easy, when in fact it's the person in the home doing all of these things that really works the long hour, because these things are full time jobs, like 24/7 jobs, and the partener that go's out to work to bring home the pay, really has the part time job, because his job ends when he comes home.
It's idoitic for people to think the partener that takes care of the house and kids, and cleans up, takes care of the parent or parents,cooking and takes care of the husband/wife when they come home from their work and does all of the household jobs and does not get anything in return are not just as worn out and tired as the husband/wife that works outside of the home, i beleive it's the husband/wife that takes care of home that needs a break more than the partener that works outside of the home.
You really need to talk to your husband and let him know that you are wornout phisically and mentally, you need to recharge.
My prayers are with you, may god open your husbands eyes to your issue.
