If I Let You Go Lyrics Meaning

in my opinion, the meaning is you are really like someone, yet you cannot show it.

You will have so many reasons for this.You cannot show your feeling because internal or external reason.
You can personally too shy, or you cannot show it because your status/condition.

my experience, this kind of feeling is suck.
It is right that you have to choose, you have to show it or leave it.
In my experience I choose to let it go. It is hard, but I never chase a man.
