Mental harassment from husband/mother in law/sister in law

Hello sir, myself Sheena married since 2012 has a girl child of 3.5years. Worked at mnc blore for 5yrs. As husband and relatives named m as a slut (just 4months of marriage) I left my job to save marriage life. Marriage expenses, jewellery,household expenses, maternity expenses, child expenses taken care by me n parents.when I left my job they started harassing more, beat me very often. That's why I joined back to work when I was 3 month pregnant n still he keep on saying it's not baby n given lot of mental harassment. Quit that job as well. Struggled a lot to save my marriage life. His family forced him for a divorce every now n then including his mom.It's been more than 5 yrs he still argue n fight for some or the other reason. He listen n follow blindly whatever his sister n mother says.They r indirectly making him to spend his money on them. Due to shortage of money he argue with me again.He hardly be truthful with m. Somehow I made him to buy an apt at native,my name is not there. his mom started staying with us permanently, taking advantage of being old n not allowing us to be together every day. Telling him to take care of her not ur child .I'm always scared abt my child future. His sister come to my house n threatened always saying this is not ur house n make a scene create problem btwn us. My question is, as I am housewife since many years, has a girl child, will this house share will I get? Is there any option of scaring mother n sister with law act? As I did not want to go for a separation, hence haven't filed any case yet. I want to lead a peaceful common man family life. Pls advice me
