One of them is lying and I don't know who, help me please!

So my boyfriend told me my best friend called me a slut, and I believed him, because he is her ex even though they dated for about a day. Not even. But when I asked her about it she totally denied it. And now I know that means one of them is lying to me, but I have no clue which one. How do I figure out which one is lying without ruining both relationships in the process. Or should I just go with chicks before dicks, sisters before misters. Help me, please.
