Me and my ex broke up and its been a month and I cant get over him 😔💔

I hear different things, and I came a long way just for our friendship to be good and back to normal. But his friends keep bringing up how he left me for a 'light skin gyal' and it hurts me and makes me even MORE angrier 😒🙈🔥🔥

I don't know what to do to get over him. He got angry because I accused him of it and he told me it isn't true and he told my best friend that its a lie and he didn't cheat or anything and wasn't talking to a 'light skin ' girl.

What should I do 😔😭💔🙈
