I dont understand

You see my outsides
And say I am fine
But the look you see
Does not come close to mine

If you stop and listen
You can hear
The screams from deep within
And you can see my darkest fear

I don’t know why
You affected me in such away
But when I saw you with her
I was blown away

You were happy
And I was not
In your mind
I was just a little black spot

I asked why it
Did not hurt you as it did me
But finally cleared my vision
And now I see

What we had was deep
But not deep enough
Because you could climb out
As I sat there thinking of all the stuff

I was weak
When you were strong
When you spoke
It was heavens favorite song

But now I lay
In an empty bliss
Without the feeling of your touch and kiss

You left me for her
And also for you
But from me
My love is always true
