problems with in-laws, mental abuse and intruding in conjugal life.

To my in-laws I'm an outsider and I have to follow them blindly. My husband even though we had a love marriage do follow them blindly. Even with a thorough marriage counciling season where the councilor suggested seperate arrangement for my husband and me from my in-laws, my husband is denying that. He is arguing as he has a house building loan to pay off. Both my in-laws are still working. My mother-in-law works in post office and has mental illness. But none cares to treat the condition properly. Now I'm 8 months pretand had to move to my parents house for my safety and security and well being. My husband visits me every week and spends 2 nights with me and provides my medical bills. I'm scared for the future of my baby and my self. Please suggest me what should I do?
