I'd like to know the answer to that also. I'd like to ask my freind of a year on a date. But I'm not sure if I need to tell her that I like her first wait a bit and then ask her on a date. Or just ask her on a date. If I was on the receiving end then I would like to be told she liked me a day or two before I was asked on a date so I could process it.
I'd like her to just come out and tell me. go somewhere quiet, that has an easy escape like a street or parking lot where the car is parked or they can catch they bus... if they say no, you can go and just stay friends, if they say yes, then you can go somewhere
Say how you feel. Being upfront and talking about things is very important.
