Can't be without you

I know you but i don't,
I could leave you but i won't.
With you, without you, i know that you'll stay,
I know that you just won't go away.
I miss you,
I love you,
I can't be without your love,
I sometimes wonder if your sent from above.
I think i have an angel in my life and I'll take that to the grave.
I have nothing to fear because you are so brave.
I just wonder if i deserve you so.
We may be together forever,
Well, you never know
