I'm 13, and my best friend fancies me. I really don't know what to do because I fancy this other girl a bit, but she's in a fragile relationship. Help me!

Tell the girl you don't have feelings for her.

It's the best way. It sounds hard. But once people know where they stand. They can move on. And start to heal!

Trust me it never get easy ;) in fact this only gets harder

Good luck

Be honest with your friend.
