Help with my ex!! I'm in junior high btw <3?

so teres this guy let's call him ralph and we used to go out but then he rudely dumped me and called me a liar and etc. because I wouldn't tell him who I had a crush on (I know what your thinking "wow that kid needs to get some") but anyways so me and his friend Jake like each other but he keeps telling me that Jake is saying bad things about me and Ralph is telling everyone that I'm a bad person and that I'm not as nice as people day I am... do you think Jake will still like me? what should I do with Ralph?? thanks xoxo
