Whaat should i do, i really like someone?

kk so heres whats happening, i had a dream the day before valentines day about this one girl and it made me realize how much i really like her, so know the only problem is what I should do. See, im pretty sure shes going out with someone currently through what ive heard since she sits right next to me( im a feral druid so im sneaky, wow players will know what i mean :3) but anyway, i cant just ask her if she does and asking her out will prob end up in me getting rejected and or getting beaten up by her bf. So im incredibly confused, and well, im also shy and asking her anything isnt going to happen, plus im not in the same social cl ( not money wise, like popular and such) so any suggestions will be good, oh and waffes would be good to, but id like the question to be answered, waffles can be given later.
