You may have options including the following: a court order or agreement specifying that the pick-up and drop-off of children will take place in a public place. Also, you may need a restraining order at some point in time. In addition to the police report, I suggest that you take good notes of any times that you or your D feel threatened. I hope you don't need that kind of evidence, but it is better to be prepared.
Protecting yourself and your D will not hinder reconciliation; it could only ensure a recon that is based on appropriate behaviour. I'm sure you wouldn't want anything else. The effects on children of witnessing these kinds of incidents can be devastating and long-lasting.
