Marital problems

It is not even one year of my marriage. I am currently pregnant and expecting my first child. My husband and I constantly fight for trivial reasons. He feels that I am not a good wife because I am teaching only for few weeks as it is part of my studies. I am only doing it so if something happens I can do something with my life and do not need to rely on anyone. He tells me that I must not come home for the current week and stay at my parent's and he will fetch me the week after. But due to my ill temper I told him don't bother. I am so fed up of this marriage. I feel like I am a caged bird. I may be islamically inclined but I am not a saint. He expects me to be a saint. I can no longer take it. I have felt hurt and sad through out my pregnancy. I can no longer take this. I have tried to over look many remarks and fights. But there is a limit and I've reached it. Could you please help me?
