Your dating must have a purpose and should be focused on what you are really looking for. There is no end of dating but the purposeful end of dating is to get married to the dating partner. As it is a serious game, you can lose easily if you would not plan. So, to win yourself a dating partner, you should.
You have to stay positive if you want to get something out of your dating. Do not keep yourself entangled with the past experiences. Take it as a lesson and move ahead with life. Just keep in mind the old saying, if you keep doing what you have been doing, you are going to keep getting what you have been getting.
