Replying to I got a question for all the girls on here...

Me and this girl Jessica are really good friends. I think I like her and am interested in being more than friends, but I'm not sure what her take on the situation is. She sorta flirts but I'm not really sure. How can I get this out of her w/out sabotaging our relationship in the case that she isn't interested? I figured girls would kno best, but any guys w/ good suggestions are welcome to post as well
