What should i do if my friend told me that he spoke to the person i love and my crush said she dont like me back
It's better to find that out your self, because what if your "friend" also likes the same person and is afraid that if you told your crush how you feel, your crush might feel the same way. It's jealousy. Never trust anyone.
Don't give up. You always have a chance.
Believe until you hear it from her
Maybe she was embarrassed to tell him the truth so she didn't
Maybe he made it up. But if he didn't, don't cry over someone who wouldn't cry over you. Trust me,this quote helps me somehow:)
