Lost update!

It's me again, I wrote in about a week ago about a violent relationship due to drug abuse. The day I wrote that, after writing it, I felt pathetic, why was I sitting on my eyes, writing a novel anon for people to read and for me to still just sit there. I decided to make a step, to you, it may not be enough, but to me, it is for now. I went and joined a playgroup that day, Sussed the mums out, chose one I trusted, told her everything, I asked her to take care of my kids for a few hours, it was hard to leave them, but I didn't have a choice, I waited for my husband to get home, I was petrified, his angriest when he gets home. I yelled, I shouted, he kept asking where the kids were, I told him he isn't going to see them again if he continues the road his on, I told him how I felt, he already knew I felt that way, I told him if he uses again I'm leaving, I lied quite a bit, I didn't have a clue where'd I go, I told him I had money he didn't know about, I told him I'd informed police, and that they will be watching the house, I told him I told the neighbours to call the police as soon as they heard a peep from him, I didn't do any of that, and no matter what I'd always let the kids see him safely, but he didn't know that, I felt awful for lying, I hate lying, but what else could I do, he needed to know I was serious, this is his last chance, I made him watch me pack keep sakes, clothes, things we would need if we left, I told him I was taking these to a friends, I did this after he smoked pot because I knew that's when his calm, he cried, I didn't, I'm sick of crying. He gave me all the atm cards, he gave me all his ID and asked me to give him $20 for lunch and drinks for work and to fill his car each week, he has no money, no way of getting it either. He spoke to his parents, told them what's going on, they have set up a bank account for me and the kids, they understand if I leave, this is his last chance. I read every single comment on that post, most told me to leave now, some told me to help. His quite sick at the moment, shaking and sweating a lot, I guess is a good sign? I don't know much about drugs, I've never done them, or known people to really them, I made it clear, our marriage will not end because he became a drug addict, our marriage will end because he didn't love or care about us enough. And that's what I'll choose to beleive. A lot of you may disagree with this. I plan to call DV and tell them the situation, I plan that one more rage episode will most definitely be the last, I've made a promise to myself and my children that this is what will happen. It's been a week now, I'd rather try and help him then leave. He will be in my life for the rest of it either way, id rather have it positive. I plan to keep you all updated with everything, and if this turns to shit and turns out I'm just being a naive fool, I'll leave and tell you all who I am. Thankyou for your support, I feel stronger and less alone. I can do this. Thankyou.
