Often in the context of professional relationships and our career, we hear the advice that we should not burn the bridges because we never know when we might need to take a walk down the same road. I believe same is true for personal relationships too. Sometimes when two people hastily decide to step away from each other, it is better to do it on good terms. I am not saying that you can be friends after breaking up but there is absolutely no good reason to become bitter enemies.
This is also the first tip that you should always keep in mind because you never know when you might have to think about how to get your ex back.
The flimsiness of relationships especially at a young age is no strange thing. It is better to know the rules of the game so that your mind is at peace even in the worst circumstances. You must know that there is always a way out to achieve some thing that you truly want with all your heart. Just keep a sane mind and a devoted heart at the same time to get the best out of any situation. Reflect and along with emotionally, logically understand the reasons why you want to get back together in the first place.
