You keep the air in my lungs

I really really don't like this poem. Just a heads up.

Please don't be oblivious.
Don't pretend like
You don't realize
You're on my mind all the time
Instead let me lead you,
Let me trust you,
And give you the best thing I have.
But you have to make
Just one promise;
That you won't run
And ruin anything we already have,
Because maybe I
Have already given you
The best thing I have.

I wish I could tell you how frustrated I am that you didn't say something before.
