Two choices: 1) Ask her out, feel like a twat when she says no 2) Don't ask her out, never know what she'd say, feelings go away, who gives a shit... Well, she's not necessarily going to say no.. Usually girls are quite friendly with you if they want you to ask them out. If she's just ordinary to you, don't bother. Oh yeah. If she's your friend, but you can bear for it to be weird for a while, it is worth asking her out anyway. Getting that confidence, regardless of her answer, will only do you good in the future.
