Part of the affliction of addiction is being a control freak. I split with a man who continued to call, show up, park across the street and use binoculars, basically stalking me for months. I didn't engage him at all and in fact had the police involved. He was obsessively possessive.
When we were still involved and I would take a day off, he would call fifty times a day (this, thank God, was before texting.) You've heard the term "obsession of the mind"? Well, it is a basic underlying theme in addiction.
Prayers for you and your child to get through this next month under protection, and with strength and courage.
