Marital conflict

I am married for last 2 years and now my marriage is on the verge of breaking up.... for no fault of mine. It was an arranged set up and both of us were from respectable families and background and made a great pair. The only aspect on which i compromised was that he was earning little less than me. But later on I came to know that the salary figure was also fake. I came to know that my husband has ED issue. I thought that its pure anxiety issue and it will heel over time. But it never got cured.... I asked him to consult doctors, but he was always on denial mode and kept saying that he will consult one. It took me over 8 months to take him for his 1st doctor visit, but one or other thing came up and he never took medication and made excuses. I never discussed this with anyone on the family... thinking he might feel bad and since this being a personal issue we will solve it on our own. In between all this, my relation with him got deteriorated due to over interference and nagging nature of my in laws. They always bitched about me with him when I am not there (i have longer working hours). They made him believe that i don't care for them and I don't like them. My mother in law is a very manipulative lady and she has spoiled many homes in past due to her complaining and bitching nature. My husband is a mumma's boy and believes every word his mother has to say. He even discuss every minute thing which I say to him with his mom. She started putting poison in my husband' mind about me and my family. They would try to find faults in everything which i do and discuss in a meeting. When i would return home every evening, my husband would start fighting with me.I used to literally cry every night due to one thing or other over which they have fought with me. Eventually they started to demand money from me and wanted to handover my savings accounts to them. I denied. This lead to daily fights. Now he don't want it to be resolved at all and want me to move out. But I have failed in my married life completely, just because I never spoke up for my self and let my mother in law become the controlling factor. As of now i don't have guts to divorce him and move out. I definitely wants to continue my life with him but can't stand presence of my mother in law in my married life. How can our married issues be resolved, please advice. Can it be dissolved on account of impotence, mental abuse and dowry demands.
