in here or in real life?
anyway...if it's here,don't bother man...look,online relationships suck,either you learn it the hard way by trying,or u learn it the smart way by listening to me
in real life,try to be funny when asking her out(don't make yourself look bad though,by acting dumb and making her laugh) there's a difference between making her laugh at your joke and making her laugh at you,but if she really likes you,it won't be a problem,the best thing to do is... try to act like you don't care(to yourself,not to her),it will soften if there's a rejection

good luck man,hope it works out
