What's the most respectful way to show my friend I like her?

I've liked my best friend for long time. A long time ago she told me, she sees me as a friend. I want to show her the love I feel for her a little for now, to see how she reacts. For example we went to the movies, just me and her. I wanted to put my arms around her but I was afraid that would scare her so I didn't. What's the best way to accomplish this without scaring or disrespecting her?

Well talking about your feelings with her would probably more successful. Then that way if she doesn't have feelings for you in that way, you don't feel like an idiot. I mean guys try to hold my hand and I tell them myself "Are you hitting on me?" and they'll reply yes, and its a very awkward moment that you don't want to experience. I'd rather have a guy talk to me first than to lay any finger on me

Sorry 2 be so blunt but the only approach is to talk 2 her.

I won't pretend to be an expert, but most of the time, when you just do something, you'll probably get a worse response than you might think.. (like anywhere from her slapping you away, to moving further from you.) some people told me (I won't say who because it could incriminate them) that girls like it when you surprise them.. from ....you could call it observation... I've noticed that surprises in a lot of cases are not what you should do. (especially with a "best friend" like in your case, because they might not think of you other than a friend, and it would probably freak them out)
talking about how you feel, is a much....safer, approach
best of luck
