Help with a crush problem?

well as a teenage girl, maybe shes willing to ually experiment with you because she feels like she can trust you since you are best friends. Im a girl so i know that you dont really think of your best friend as a guy but just as a friend. So its different to kiss some guy without commitment and to kiss your guy friend. I mean its almost like kissing another girl that she's friends with but it not being awkward because your a guy, yet she can trust you not to take it the wrong way. I deffinately dont think you should tell her you like her because it could ruin the friendship, and if she is just experimenting with you because she trusts you, and you tell her you like her, she will feel violated. Like she will automatically think of you as some guy that almost used her in a way rather than just a friend. This is weird but if you two are close, its almost like when a girl has a gay guy bestfriend. Like she doesnt mind changing around him or anything because its not like he will see it ually or it will be awkward. Now imagine that girl having had changed infront of the guy only to find out he was streight? It's like she would feel insecure and violated.
