Second time around
Some would say that going back works better than the first time because you realize what mistakes were made and you know how not to make them again. But, this is not true for everyone. Sometimes you must let second chances be a time when you work on yourself. Take it as a reprieve from the stupid things you or the other person said and did that caused the first time to fail. However, when there is no closure, and no valid reason why it ended in the first place, you should explore the second time around to gain something that you missed out on the first time.
