I am so happy for you that you were able to face your fear and contact him. That is great. It must have been horrible. It's good that it doesn't send you into a panic attack anymore, that's the best thing.

The only thing I would say is to make sure he can't contact you back, because that would make things worse. Plus, if you started a conversation with him through this it just wouldn't be a good thing. You've said your peace but I wouldn't want you to have to deal with a response he would give and it would make things much worse.

Take care, and I wish you all the best,
