Be safe and take care of yourself. Don't hesitate to call the police if he does show up.
Unfortunately I understand. I used to alway sing "I'll be dead when you're dead you rascal you" in my head, about my Dad. We did reconcile, but never had any real connection. I had forgiven him and I wasn't thinking this with hate or anger, just a longing for relief.
He was incarcerated at 80 for trying to shoot my Mom with a rifle, had treatment in lockup, got sober, had a few good years then Alzheimer set in and died a few years later. It was a great relief when he passed. I didn't feel guilty at all, having dealt with forgiveness long before.
