Why my ex spreads false gossip?

Anonymous
He broke up with me a week ago saying he doesn’t wanna date now and maybe we can try later (?) after that he says everyone in the school i cheated on him ( which is a lie) he says he learned this that day so its not the reason apperantly but all of friends around us call me cheater now on social media etc. why he is doing that? I didn’t do anything wrong i only had a guy friend which i talked a lot and apperantly he has a thing for me ( again people saying that not my friend) what should I do? I texted him many times explaining even saying you should have inform me if I wasn’t allowed to have a guy friend. He just completely ghosted me doesn’t even answer. Should I talk to him at the school or just ignore everyone and everything. How long people will act like that? I still talk to my guy friend cause its just talking on my side. I really liked my ex and imagined dating thorough high school but is he using this as an excuse to date others? Cause its understandable at this age boys wanna date many but he should have be man up and tell me. I have a kind heart and dont wanna people think otherwise. I hate highschool dating.
