I think it's very important that you go with your gut instincts here. If they are telling you that he is dangerous and you cannot trust him, then go with that and leave well enough alone.
You and your family are much more important than this guy having his day to apologize...even if he may be truly wanting to apologize....it's time to drop it and live your life safely and in peace.
If you are feeling threatened....then by all means go to the authorities. Remember that safety for you and your family is top priority...not this guys feelings or intentions.
Be well and safe
