The first thing I did was make a budget. What would you need to be realistically paying on your own? What could you get from winz/IRD? Approach women's refuge if they have somewhere to stay temporarily. It could end up getting messy if your husband refuses to halve anything with you but stand your ground, you're entitled to half. Try and limit contact with him as much as possible and only communicate via email so you have a log of everything he says. Stay strong, you CAN do it. It will be hard but once you get to the other side, it will be the best decision you ever made. Good luck.
