It hurts

Loving someone who doesn't love you

It hurts to love someone who doesn't love you in return.
To long to talk to them, be with them, have them hold you in their arms for hours.
They don't want the same from you.  They want space, they don't understand you longing and pain.
You can sometimes get close but you will never really get to where you want to be.
Just let it go.
Put it all behind you and let it go because it hurts.
