Thank you all for your replies. I have to admit this encounter was pretty scary. However, before I walked to my car, I walked toward him and got real close to him and ran my hand down his tie, looked him in the eye and told him that, "all I want for him is his happiness, and he appears to have many regrets". I caught him so off guard. When I did this he moved closer to me, but told me to get away from him. It spoke volumes and I guess I wanted to show him that his bullying meant nothing to me.
I could not sleep last night thinking of all this. I guess it is time for no contact again.
