Hi
So sorry to read your post and see how upsetting and worrying your boyfriend’s coke habit is for you.
If you would like some help please contact us at Icarus Trust. We are a charity that supports the families around people with addictions because we know how hard this can be. We have trained and experienced people we call Family Friends and you could talk with one of these if you get in touch.
You can contact Icarus Trust on help@icarustrust.org or visit our website http://www.icarustrust.org
All the best to you.
