I too left my coke addicted husband.Walked away from a 17 year relationship as I was suffering emotionally. He harassed me for months. I am ashamed to say I seeked solace outside of the marriage as a way out. (I do not recommend) .. he stopped harrassing me after 16 months and now has moved on and leaves me alone. What I want to say is. I am in a better place now mentally and I will always love him but drugs ruined our lives. If anyone is contemplating leaving it will be tough at first but it gets better.
My ex husband now no longer contacts me or his child… which is a shame for my child but our life is much calmer now
