Stay or leave?

B
I'm confused, don't really have friends I can talk to about this and I don't know what to do. I'm not happy with my life and feel like I need to be alone. Are relationship isn't working ne more I have tried to leave him 2 different times in the past 6 months but he talks me out of it.we have been together for 9 years, no kids tho. We have moved states to keep him away from drugs and that's why I tried to leave but he said he would stop but I don't think he has. He has a problem and it's meth. I'm done talking to him about it and he won't get help. Should I just pack and leave while he's at work?
