As the house is in joint name of both of you, you cannot stop his entry or use his house and filling complaint under DV Act, to prohibit his entry in the matrimonial home will not be allowed, wrong suggestion given to you.
As far divorce is concerned, that will take ample of years to decide and as in your case it will not be so easy to obtain if your husband doesn't agree for it.
The husband will like to have his part of the property and this house will have to be sold to pay his part of money invested by him to buy the property. Without this he will by no means agree for divorce by mutual consent. If you want to continue living in the house and not ready tom sell it, than you will have to pay from your pocket the amount of money he invested in the house, that will make you pauper with the responsibilties of two children and EMI of the bank.
You husband is supposed to share for he children's maintenance which if he refuse you can ask through court but for yourself as you are in job you won't get financial relief.
Easy said than done for anyone who speak of taking divorce in India.
