Child responsibility

This is Mercy from India...I needed some advice. I have been married for 6years went through a separation early after 3months of marriage due to interference from in laws.. then after 3 years my husband joined me at my father's place as he was almost sent out due to property issues. We were peaceful, was blessed with a child then, who is 2years now, conceived again in a short span and have another child who is 7months... but when I was 6months pregnant my in laws again interfered causing problem, and I was going through depression as my husband was not by me to understand my turmoil. At the same time he had restricted me from marriage not to have any connection with my mother and her family as they were unhappy about the proposal but it was my father alone who came forward and stood for this marriage. Ever since the time he left me when I was 6months pregnant he just comes once in awhile, any small confusion he avoids us fully. Now, I'm pregnant for the 3rd time and 3 months. He tells me I have to join him and puts all conditions against my mum. But when he wasn't there I had to spend few days with her so that I could take rest with my children, yet I return home when my maid is around and doesn't travel out. Please advice what step I should take, he is not one who is willing for a counselling he believes what he is doing is right... i need a leading as to what to do. Request you to advice me.. regards, Mercy.
