She had built a wall around her heart
Then he came along and the wall fell apart. She went past her wall only to realize it was still full of Pain. She could finally see that maybe love would never be the same.
For that she has to accept but, knowing him and loving him has been a joy she will never regret. She has to move on and back inside her walls.
The time they spent together she shall never forget. She leaves with one hope, that he will one day see the love she gave and what could’ve of been. Although she doesn’t want to, the time has come to let go of those feelings and leave it all.
He will never love her back and that she has to accept. So away she goes with a silence of hope still beating in her chest.
