Not Sure

I love you for saving
Without even trying
But if I were to say it
I'd feel like I'm lying

I want to be close
But I'm not sure I am
You need to open up
But I'm not sure you can

I hope that we last
And my hopes have been high
My doubts I look past
And I hope you know why
I think how I do
I'm head over heels
But not sure it's for you
