You can contact the Women's Centre. They have great atmosphere and will put you in touch with a counsellor and all. Sometimes, if you qualify, the help is free...good luck!

There are lots of place where you can go and find help. Start a your woman's center they will advice you on what you need to do and don't worry about the money, if he has money they will make him pay. Good luck and keep us posted.
Go to your local community services office, they should have resources for you. I was in your shoes once, being a stay at home mom. I finally started working and am finally making enough money to leave. I just started looking at apartments. If you are not in a dangourous situation I would suggest trying to get a job and stick it out for a few months so you can save up some money. If you need to leave now you may have to go to a shelter, or stay with friends or family until you can start working. Good luck!
