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.

I think it is unfair for your husband to make you quit your job but at the same time, not compensate with helping you out financially and worse still, forcing you to leave your home just so he can rent it out to supplement the household income. Obviously, a single salary situation is not working for your family and you should make your husband understand this. What good is it for the children and their future if you are a stay at home mom who does not get any support from their dad and also, with no proper home since it's rented out for money. Talk to your husband -- maybe you guys can come to a compromise. You can suggest taking on a job that is flexible in terms of hours (maybe part time?) so you can contribute to the household income and have more time for the kids.
