Too ambiguous?

[Reags]

There was a name I wrote in the sky
Not so high you couldn't see it
it wasn't meant to make you cry
I guess I'm one of those bad boys

But now its beating me
its playing on my mind
I shouldnt feel this way
When you called me friend in half the time

How Could I
Misjudge this so much?
You wouldn't make that mistake
Because you wrote the book on me

Out of the corner of my eye
I can see you're not believing
I gotta wonder what to try
When plan D's failed for the third time

But now its beating me
its playing on my mind
I shouldnt feel this way
When you called me friend in half the time

How Could I
Misjudge this so much?
You wouldn't make that mistake
Because you wrote the book on me

I wont walk away
Unless you say
I haven't heard it yet
So I'm sticking round

This is the story of my life
Misinterpreting the meanings
I crash before I fly
I guess I'm one of those sad boys
Again

Can you guys tell me what youg et from this song narative wise? I just wonder if its too ambiguous to convey the proper meaning.

Cheers for your help. Any criticism welcome.
