Hello BlueBeauty
I would say yes, its the right thing to do. Its up to you whether you want to remain in contact or not, and if you’ve said no, then thats the right thing for you. Its generally the only way to avoid the abuse is just to cut all contact. You also handled his threat to OD well by reporting him. It doesn’t matter what he wants this is now about what you need.
If you need to, you can block him, if he won’t accept that you don’t want any contact with him, and tell him you’ll report any further unwanted contact as harrassment.
warmest wishes
