Threatening anyone is not loving them. If you are nervous around him he’s not for you. This is advice I should have given myself btw!!
Do you think he would actually ‘out’ you to your family? Or is it an idle threat to control you?
Would your family believe a stranger over you?
My advice would be to go to the Police. There are lots of laws around threatening behaviour. And lots of laws about what data/ texts/ pictures etc that people can share on line. A call from a Police officer may be enough to give you peace of mind that he won’t do that. Then you can move on.
I wish you happiness and peace, I don’t think you will find that with him unfortunately.
