I have a huge crush on my best friends sister, i can not work out whether the IOI's she gives me are as friends or as more than that. Honestly though, i have had every body language related IOI there is off her. Ill be honest and say that i dont care what my best friend thinks if i could be with her, but if i were to make a move and get rejected it would be impossible to live down. And i could end up losing both of them.

I clearly have one-itus. But, i need to go for it, or put it past me, I do not know what to do.

There is nothing in a book that can make this decision for me, but some advice would be helpful.

You don't have one itis... Because it sounds like you have a chance with her.
Make a move if it works, it works, if not then move on.
