Hi SSS,
I’m sorry to read your post and see that your boyfriends drug addiction is having such a strain on your relationship.
May be you would like to contact us at The Icarus Trust as we are a charity that provides support for people going through what you are having to deal with. I could put you in touch with one of our trained and experienced people who would understand what you are going through and would be able to help you answer some of your questions. There may be other support near where you live that they could let you know about.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
I hope this helps.
All the best.
