my boss moved me here

i am working for this company for almost 1 year now ,after about 4 months my boss asked me if i want to manage a branch about 100 miles from there, he told me he will pay for my rent for 3 months which he did he told me that i would make at least $2000.00 a month on commision or he would pay me salary that promise was good for two months than he reduced my salary to $1500.00 a month if i wouldnt agree i just can leave , well right now he is thinking about closing this branch and there is no work in this town other than minimum wage casino work i can not afford to move ,my husband works as a taxi driver and makes about 30 to 40 dollars every day (12 hrs work day) i do not know what to do if he closes this place, can i get any severance pay if he lets me go and closes this office
