Hi Cathey, I so sorry for your loss.
Please don’t feel guilty, I’m sure you did everything you could to help your boyfriend.
Addiction is so cruel- turns a kind and loving person into someone we don’t recognise any more.
I’m sure he knew that you cared for him , the addiction just takes over their every thought, word and action.
Perhaps you may benefit from contacting a bereavement counselling service.
Please look after yourself
Sending hugs ❤️
