Welcome to the Sober Recovery family!
I'm sorry that you are hurting right now. It is painful. It is the death of a relationship.
The signs of grieving are:
Denial
Anger
Bargaining
Depression and
Acceptance
They come in waves. Some can last for a few days or a few minutes. These emotions are natural.
I agree with the above poster that detaching from him (no contact) will help you with your recovery. He has counselors to help him with his recovery. Are you seeing a counselor or attending Alanon meetings?
Please make yourself at home here by posting and reading as needed.
