Me (19f) and my ex (21m) were together for 2 and a half years before i broke it off about 8 months ago. We broke up on our vacation in greece with a bunch of friends. I was going to break up with him after that but he left me no choice as he made me cry on the beach somehow. I have made a lot of friends through him and throughout our relationship i've literally encouraged him to hang out more with his friends instead of only playing games with them and talking on discord. My 2 girl best friends are literally the girlfriends of his friends and when we hang out sometimes they tell me stuff that he's said to their boyfriends. Not much tho since their boyfriends also dont really wanna say what it is so basically me and my friends have no idea what he says about me to people. Only thing I know is that he's lied that he broke up with me and that's why I cried on the beach, which I think is such a childish thing to lie about. And he's talked stuff about how it was my fault he broke his finger when punching a wall because he got mad at me(which happened long before we broke up btw so it's really old news and he got mad because i wanted him to go to the store without me to get food). Mind you it really wasn't a messy break up, no one did anyone dirty there was no cheating and we really did like each other but we would just argue about so many things and never come to a solution. And I was willing to stay friends with him. He however didn't want to so he told me he will block me everywhere except my phone number in case anything happens. And I was okay with that however he has me now also blocked on his number before I had even tried to call him and talks shit about me to EVERYONE. He's had a new girlfriend now for a month and still it continues. I know of a few stuff he's said but my friends tell me there is many more that they also are not really sure about. I want to talk to him and find out why he says all this stuff yet he's blocked me everywhere and can't face me. Yesterday I saw him at an event with his new girlfriend and I would have gone to talk to him if she wasn't there because I really don't care to break them up and stuff or make a scene. Also the girl he is with now is a girl from our school a year younger than me and she has seen us in the school we used to go to together plenty of times. At that event I asked his friend something and he completely ignored me and acted like I don't exist, but when my ex isn't there he's talked to me just fine. And since I live in the capital city of my country and it is big but everyone is still connected, I feel like he's talked to so many people and everyone knows stuff about me before they even know me cause I also keep to myself kinda. And also one of his discord friends took me out on multiple dates a few months ago and I wasn't really feeling it and he could sense that so we stopped going out(and he also studies jn another country so there is no point yk). And of course it reached my ex. 2 weeks ago I told one of my friends something about her boyfriend that she didn't know that my ex had told me ages ago and her boyfriend has been lying about it for a long time and I just couldn't keep it to myself. Of course her boyfriend was mad at me and I apologized through chat and now at that event which he was one of the hosts I saw him and we greeted each other normally with a hug so I figured he must have gotten over it. But I also found out that my ex has talked to him how Im trying to ruin relationships since it's "not working out for me" (his discord only friend that took me out on a date). And I just feel like he so easily lies about me and people believe it whereas I literally don't talk about him cause I don't care to. I don't know what I should do, I wish I could talk to him about this but there isn't really a way to reach him without looking desperate, since he's already lied to so many people that he broke up with me and that I cried and I was desperate. I really need advice on what to do at this point because Im also looking to build relationships with people but if he just keeps telling everyone stuff about me behind my back I feel like im doomed to fail. I haven't done anything about it and I feel like I should stand my ground instead of letting some childish man talk shit about me to everyone.
