"Maybe both of you just haven't collected enough stories to tell each other yet. Maybe ALLAH will finally bring back the person you dearly love and miss when He sees that both of you have collected enough stories to tell each other. And even if you know you will no longer meet the person you hold dear to your heart in this life because that person left this world, don't despair. That person is waiting for you to live a life full of passion, so you can tell him/her all about it when ALLAH reunites both of you in Paradise. So, live your life and decorate it with ALLAH's laws, so that when He decides to reunite you again, you will be able to tell that person all the stories that accumulated in your chest while you were waiting for them.
Good relationships between people never truly end. Sometimes ALLAH just puts them on hold, so both of you can collect many stories, retrieve lessons from them and grow. Then, when ALLAH allows both of you to reunite, you can tell each other all about it and watch your relationship getting stronger and more beautiful. So, live. Even if you're waiting for someone to come back whom you know still lives under the same sky as you, live. Live while waiting. Just live and fill your life with ALLAH's verses."
