I don't deserve you

What did I do
to deserve someone as good as you
I'm not the best I'm not real good
but you seemed to help me through
I haven't done everything I wish I should
sometimes I only wish I could
go back in time and change it to
always and forever loving you
you are always here
I have nothing to fear
but fear that I will fail
for you I want to be perfect but I know I'm nothing near
so all I can give all I can do
give you my heart and say I love you
