Why would the joke be on you? It is just another experience in life telling you to move on, this is not the right one for you. I hope he /she did not make you feel that it was all of your fault, some people are good at that. It took me a few to find the right one but I have no regrets! Just think positive, I realize that it is difficult at times, but when the time is right it will happen in the meanwhile, enjoy life because it is tooo short to be miserable and I try to help negative people everyday but I am nomiracle worker because I feel that we all have some joys in our lives, if we think about it.
