To: How do you know I blew it? I’m the best there ever was or will be.
Me: If you are so “best” why is she your “ex girlfriend” and why do you think you have to write her a song, to try and get her back, after being a real s*** head with her, before, so you said?
“I’m the best there ever was or will be” – at what?
You say yourself she is your “ex”, ex to me means “gone and lost forever”, obviously you think it means something else, whatever that might be.
I can’t comment on your song, because you are a different age, culture, background and just about everything else, to me.
If you feel there is any chance for you, why not send her an e.mail and profess your love for her and do it that way instead and then she can decide if she is going to reply to you, or not.
Singing her a song might not come out the way you want it to and might be a mind f*** for her instead, because you are not writing from your heart, but singing from your head, sort of thing.
Surely there are lots of other girls you can choose from wherever you hang out, that want to be with you – so what is so special about this one?
