It will be best to move on, you can never cry over someone who was never yours in the first place. It may hurt but the thing is, if the person is really in to you, he/she will find a way to make things work and turn the "friends" status to something official and not just be after of the benefits they get but the companionship and fulfillment they enjoy being with you.
I always believe in the saying there is always light after every dark moment >>so someone better or even the best will come along.. so smile
