Hi Irchem,
It must have been very difficult to make that choice to leave the relationship. As you said, hes been given so many chances to change and seek help.
Its very exhausting having a loved one with an addiction. My husband and i are mentally ,emotionally, physically and financially worn out supporting our son, for years.
Your health and well-being is important, you can’t have him drag you down any longer.
In my opinion you have done the right thing, you have to be cruel to be kind sometimes.
At least you tried, and you can hold your head high, knowing that you tried.
I wish you well for your future and I hope your bf seeks and gets the support he needs to get on with his life.
Take care
