What should I do if my husband always threatened me to quit my job to take of children? The last I did so, he not just don't give full support, he force me to move out of house with children and my elderly parents, so he can rent the house for income.

Sorry but to say this sounds horrible. Your husband should be the one responsible in finance since he forced you to quit your job and lost your income. You should talk to your husband and discuss what are the other alternatives to solve current state of financial problem other than resolved to move out of the house to get the rental income. E.g. resume back to work, arrange someone to take care of children or send them to childcare, and etc. Hope you and your husband can work out something to have a happy ending.
