My crush told me "that's what friends are for"?

We're seeing each other quite frequently given our busy schedules and I thought there were some pretty good signs of her having some interest, but I could be wrong.

Today we were having some deep conversations about a problem of mine and it ended with her saying to me that I could tell her whatever i wanted, and that "that's what friends are for".

Could this mean a total lack of interest about something more than just friendship?
