Whats a promise???

What is a promise to you,
for you know not what a
true promise

You made me promise
to never let you go,
no matter what happens,

And till this day still
i have kept that promise
and will never let it fall,

But that one day,
that you called me over,
I knew it was over,

For you were doing bad in
school,
you tell me
And care for you so much,

And what do in life,
I accepted to break up,
So you can live a great life,

But since that day we promised
i have yet to let mine fall,

For you have failed,
and let me fall

I loved you so much
and still do right now,
Letting it go is the hardest
thing

I have had to do in
life right now

I know now that a promise,
is not always forever
and Forever is not always a
promise,

I will still take you back
But it would have to wait.
For i just don't want the
same thing to happen
one more time.
