How can i deal with a guy who won't take no for an answer?, I have a friend who is a guy that I don't want to be friends with anymore because he won't take no to me dating him for an answer. I usually say we aren't alike or we don't have anything in common because I don't want to be rude, but it is starting to get to me that he acts cold to me when things don't go his way, I have told him numerous times I'm not interested but he always brings up how my ex boyfriend was good enough for memy ex boyfriend is a sociopath who manipulated and abused me for 3 years (i know I'm stupid). I don't think he understands how relationships are supposed to work or he just wants something from me, maybe to mummy him as he does have issues with his mother. He is a LVM who watches porn, plays pornographic games and is just very misogynistic. I don't want to be his friend anymore but I feel a bit threatened by him, especially because he has threatened me multiple times to message my ex boyfriend. I'm not sure how to go by it. Please any help would be appreciated.

Thank you x
