again.... options are incredibly limited for most people. That's why we have shelters at full capacity, limited budgets, priority ranking, and safety. Some shelters may not be safe for mother with children as it's probably full of male drunks/drug addicts. Typically abused people do not have friends. Social Services are not always helpful. They wait until there is serious damage which is usually too late.
There are millions of women and children in USA alone who are being abused. We can't help them all. All I can say for them is - try to find an understanding friend or relative to live with for a while until you get back on your own feet and to get your legal matter settled (filing domestic complaint against spouse, etc).
