The guy that really meant to me hate me now..bcs there's a girl who backstabbed me. Help ?

There's this new girl ( Skye ) at my new school. She's pretty close to my ex bf ( Shaun ). He's not my ex bf actually, we loved each other but I'm not ready to get involve into anything serious. So we just give each other a space, but he still texted me some things to make my day. Suddenly, me and Skye became pretty close and she started to talk about Shaun all the time. And the thing that she talked about is not good at all, it's like she's talking s.h.i.t about him. And I just listen to her without saying anythng. There's a time when she started to ask me whether I still love him or not, I just said "I dont want to talk abt him anymore, okay?". And that's just it. I've never talked anythg bad about Shone, but then last night i got a text msg from shone he said " I hate you, Skye told me everything about what you told her. I thought you really love me, turns out you really dont. I hate you, you're messing with a wrong guy". I dont know what to do anymore, the guy that I loved hates me. What should I do?
