My bestfriend i cant marry

You're always there
you've been with me through thick and thin
at times the rainbow got bold
you knew just how to do it to turn it into its wonderful colors
yet i couldn't see us toghether
i could see you as the best man
i never was able to see me and you walken down the lane together saying "i do"
suddenly theres the turn in my life
where i see you as a man
someone i might want to spend my life with
by any means im stuck on the fact
that i cant carry your last name

please comment and rate; i'll return the favor
thank you
