help or advice

hi my name's Jenna and I'm hoping to get help with something I've been dealing with. so I dated this guy's for four years and he was super mean and rude to me he was never nice he abused me in everyway shape and form. in tenth grade I finally said enough is enough and I left him and idk if anyone can relate or not, but when we broke up I remember being so mad and telling myself he did those things because he loved me. but it's been three and a half years and he's still bothering me he's lying and telling people I'm trying to charge him and ruin his life he's telling people to tell my boyfriend's mom to keep my boyfriend away from me he tells people I've abused him telling him he's worthless and that I've made it so he can't go back to school and I've told him to end his life he tells people they don't know the real me and people believe him and now I'm scared to go anywhere because his family is really big and knows everyone in this town. so my question is, is this stalking or harassment or bullying and what can I do about it any advice would be helpful
