Temporary

Four years. Four years she erased of our friendship so she could have him.
She couldn't handle having us both?
So, in the end I get to learn that a boy is more important than our years of friendship.
Stupid Leah, you should have known.
You should have known that she didn't want to hang out with you because she liked you. She wanted to hang out with you because she couldn't find anyone else better at the moment. You were only good when there was no one else. 
She used you. She walks away without a scar, while you paint a smile over the obvious scars she left for you.
As long as she has him, she could care less.
You were temporary. Maybe you still are. I wouldn't be surprised if you are.
She molded and shaped you into someone that you were not. She fooled you.
He'll walk away from her one day. He'll walk away when he sees her the way you do now.
She'll try and weave herself back into your life. She'll try to act like she cares about what has happened since she's been away.
In reality, she won't have a clue.
She won't have anyone to take her back in.
When you push people away, don't expect them to welcome you back as if nothing happened.
It's taken a long time, but you've finally closed yourself in.
Not letting anything out, nor anything in.
It's probably safer that way.
