Girls , what does it mean when a girl says she trusts you? What do you think of this situation?

So, this girl said to me that she trusts me. We seem to be quite close, I think. We've known each other for two years. She's always asking me for advice on random things in her life, like her outfits, or if this message is okay to send to a friend etc. She'll send me selfies of her now and then, like spam me with them or Snapchats of her singing through facebook or What'sApp with her singing.

We have met a couple of times, the first time she told me she felt really comfortable around me, the second time she looked nervous. She teases me now and then on things I write like picking up on typos. So, what do you think is there interest here, or just friendship?
