erick this is a tuffie
see the thing is, she trusts you. alot obviously. seems like alot of the wrong boys are knocking on her door right now. and she obviously trusts and likes you alot (even if it is just a friend *right now*

) i wouldnt say anything yet
just continue being there for her
continue being someone she can trust and hang out with and truly be HAPPY with you. and then eventually she will see "oh man. erick makes me estatic"
and everthing will fall into place :d
soon enough she will realoze (she probably already has) that you are into her.
you do have lots of patience LOL. just keep it cool for now.
