Go to Family Court in your area and speak to a family assistant or other professional
There about your situation and ask that they help you file a demand for spousal and child support from your husband.
You can also try contacting your local Bar Association and as for the pro bono family law
Or matrimonial department and see if someone there can assist you.
Your husband cannot simply abandon you and the children without any means of financial support.
It is against the law and he will be forced by the court to provide you and the children with support.
