Hey Chelsie
I’m not sure what your answer is but do not feel guilty about your email. Having a loved one as an addict is truly horrible and what you told him was the truth about how you feel and what you went through. While my son was in rehab, we had a family therapy day, part of the process was to tell your loved one how you felt when they were so crazy/angry/abusive/manipulative towards you but follow it up with the positivity and why you love them. It is the addiction that is horrible not the person.
You must do what is right for you, but don’t feel guilty for letting him know what his addiction has put you through, he will probably feel shame and self loathing but hopefully he can continue his path of recovery. It is an emotional roller coaster for everyone. I talk through personal experience but you must do what you feel is right for you.
