Messy break up

So I recently broke up with my boyfriend . He seems like a completely different person now . His friends are all astonished and they’re concerned for me . He’s been spreading our screenshots from private conversations and telling people that I asked him to call me so I could use my phone as a vibrator and some other shit that isn’t true . I told him a lot of stuff in trust and he’s just telling anything to people and if they ask he will give them information and spread lies . I’m honestly worried that it’s gonna get around school and he’s gonna release everything I sent . Help!!!
