Jealous

What happen if the one you loved
The one you always wanted
The one that you've been waiting this whole time
The only one that can complete you in this world
The only reason you finally fall in love again
The only reason you can hear your heartbeat every time a single message received
The only one that can bring smile to your sad face
The only one that matter is taken.
What will happen with the love that is not yours to take?
