A particular person who is also living with addiction may not show remorse.
Addicts in general are like everyone else and feel lots of emotions, including remorse some of the time. Drugs or alcohol can mask feelings. Shame can make people hide their emotions. Family members who are exhausted by the intensity of loving someone with an addiction can miss the remorsefulness. I am so sorry that your loved one is at risk. It's a scary time, and a lonely time. Maybe "talking" on SR can help? I'm glad you're here.
