I need some advice..!

i am married to someone who i thought i would be with for the rest of my life we have only been married for 3 years this July! we have 2 very young kids2 1/2 and 1 1/2 . but i am at my wits end!! my husband has very high expectations of me. We are both working full time jobs, I am lucky enough to to get to bring the kids with me to work so we dont have to pay for day care for some one else to raise my kids! If any of you have ever been able to take your kids to work with you at a young age you know how hard it is to keep them entertained, and out of everything! my husband thinks it is a walk in the park and i am just being lazy.. he also expects me to keep the house spotless and cook dinner every night by the time he gets home from work. I have enough energy when i get home to do a little bit, and when i dont get it all done when he wants it he flips out! he begins calling me names and cursing at me.. calling me a lazy b**** and that i am worthless! it is a constant fight all the time! and an hour after he yells at me like clockwork he appoligizes and expects me to forget all of the hurtfull things he has said to me... he doesnt understand why i am so tired alllllll the time he never helps out the babys either. He always has time to do what he wants and when ever i ask to go somewhere or for him to watch the babys for a little bit! we are fighting again! on his days off he will not even watch the kids he makes me take them to work with me, rather than watching them and letting them play at home rather than being confined into an office. I dont know what to do!?! I tell him all the time that he hurts my feelings and that it is hard for me to forget that he says that stuff to me, but i also think that is why he does it to make himself feel better. I so badly want to be with him for the rest of my life but it is not fair for me to have to put up with him talking that way to me ! and then it is not fair for my kids to hear him talk like that to me and i end up not being as good as mother as i should be when we are fighting...! Also i have asked him about marriage councling and he said he will not do it.. Please help i dont know what else to do!?
