Not sure

He came back
Back in my horrible fucked up world
He made me happy
Made me smile
But he already left once
Well I left him
I want to be with him again
But yet I'm not sure if I'm ready yet
I was starting to fall for him so I left
What if it happens again
I don't know what I would do if I did fall
He doesn't want me how I want him
I don't want to get hurt again
