Okay, so my sister just went through a breakup with her fiancee and the way I see it, it’s a good thing because it’s just opening a new opportunity for her.
They say one door closes so another can be open. The choices that you make are like keys. When you give up something, then you are giving up your “key” in exchange for another one so that you can open a new door. When her fiancee left her he had exchanged his key to their relationship, in order to attain another key to open a new door with this girl he liked. What lies beyond that door, no one knows, but whether or not he likes what he finds it is too late to retrieve the old key to his old relationship. The only thing left is to continue exchanging until you reach the right door for you.
I’m not sure if you understand that, but that’s the way I see it in a positive light. And I believe that my sister has exchanged her key in order to open better opportunities for herself.
