boys💩

I've been talking to this kid for about a week and he super nice and what not but after he claimed he liked me he asked one of his friends about me and she had the audacity to LIE AND SAY ALL THIS STUFF ABOUT ME THAT ISN'T TRUE. he now no longer wants to talk to me even after i told him non of it was true. she claimed i sucked off 5 dudes who were significantly older than me and said that because i like females (as well as males) that he should stay away from me. I'm pissed. I've never done ANYTHING sexual and I've never been friends with her. she knows zero about me. what do i do?
