Honestly I think the best approach is the straight approach...ask her out...make sure she understand your intentions...don't come on really strong but just don't leave any question that you may want to investigate the possibilities of a relationship with her.
Just be confident and don't worry if it doesn't work out...there are lots of women....as soon as you think you couldn't find another won you will.
Completely baffled by a backward indication
That an inspired word will come across your tongue
Hands moving upward to propel the situation
Have simply halted
And now the conversation's done
