I don\'t know what it is with me

I don't know what it is with me
After him I'm just not who I used to be
Every guy I find just isn't good enough
No one can compare to the first love I ever lost
I'm afraid for any chances I take
Because everyone could end up with me and a heartache
I don't know what it is with me
Loving him has changed who I used to be
My heart doesnt open up to anyone anymore
He took the key after locking the door
I trusted him not to destroy my heart
I cant stay away from him I can't stay apart
I don't know what it is with me
After all the lies he made me believe
And I'm still waiting to take his pain away
I love him, I want him. it's for him I pray
I don't know what it is with me
After him I'm not who I used to be
