Thank you all for your feedback!
@ BoringGuy & Marcus:
I don't think what you two are saying is irrelevant at all! I've been thinking and you two are absolutely right! I have no right to declare her sexuality for her...and it really is selfish of me. I've decided to tell her I have a crush on her; if she says she's straight I'll just respect & accept!
Thank you for being honest : )
