Iwant to break my lease because of my slumlord,can i?

iwant to break my lease because my landlord doesnt fix anything. my childrens bedroom dosent have heat and my slimlord tells me to switch bedrooms with them. theres just storm windows no real windows, 2 huge holes in the yard from them digging for the sewage, floors caving in and he tells me to put a board over it!! i wrote a list of things that were wrong when i first moved in a year and a half ago and NOTHING is fixed. any advice would be grealty accepted- i just want out i dont care if he fixes them or not i just want out-NOW!!!!! do u think if i threatened to report him he'll just release us of the lease? thanks
