my ex and i got into a fight recently. he got really mad at me and is still upset about our breakup. he said to get me back for leaving him he was going to spread rumors about me the guy im currently talking to. he even emailed me the long horrible message he was going to send. some of it was false, some of it was exaggerated, and some of it were private secrets i dont want anyone to know. what should i do? he keeps threatening me that he's going to send this message out to the guy im seeing.
