Alcoholics are compulsive. It is a disease of compulsion. She may feel suddenly compelled to contact you, and that will be the disease of addiction in action.
It is never a good idea to take any behaviors of an alcoholic in active addiction or newly in recovery to heart. The brain of the alcoholic is still in great dysfunction and will be so for the first one to three years of sobriety.
It is best to remain no contact as much as you can.
