I don't know

You look at me with confusion,
"you don't know?"
The confusion has turned to anger,
"How can you not know?
Am I not good enough?
Am I not strong enough?
Am I not pretty enough?"
I cut you off,
"Stop, it's not you it's me.
I'm the one that's not strong enough..."
I am just that,
not strong enough to jump in with you.
I rather stand on the sideline,
I'm too scare to get hurt,
I'm too scare to commit,
I'm barely strong enough for me,
let alone the both of us.
I can only just manage myself,
I can't pull you into my world.
It's not as bright and clear as you think,
underneath it all, I'm a 1000 piece puzzle,
only the edge has been made.
There is still 950 pieces to go,
most of them still need to be flipped over.
In this moment of time,
when you have opened yourself up,
when you are completely vulnerable,
I am completely clueless,
I do not want to lie to you,
I can not hurt you anymore.
I can only try to ask you to understand.
"I don't know how to love you,
because I don't know how to love myself."
