I want to break up with my boyfriend he scares me when he's angry and just generally make me feel very low. The only problem is he threatened to do things if I ever leave him. It's a bit hard to explain but I'm not worried if he hurts me but he has things that are mine and knows things that will ruin what little relationship I have with my family. I don't know how to end it with him without making him angry. Any suggestions please I really don't know what to do
