I did exactly the same thing- I withdrew my statement and support for the case as I believed all the promises and that it was a one off use etc- the police are pursuing it anyway for my case though. im so sorry, I feel we are all part of a club none of us wish to have ever known about. Don’t feel ashamed about this it sounds like you’ve gone above and beyond and blocking him sounds like the right thing to do but please just be careful and safe in the meantime. My ex, (who I still love of course- its a curse isn’t it) is ringing me from prison and sounds like he is really depressed now as reality has hit him id imagine, but like others have said we don’t know where their rock bottom is and until he is no-where near you then your ex may not hit it either? my family are now aware of what my ex has done and don’t hate him despite him having done loads and loads of awful things (not just small stuff), they feel quite sorry for him due to the drugs issue but still feel he should not be near me. you may find others think something similar about your ex too.
