Riddle me this

Why is it okay for you to wake up beside me
But not be brave enough to define us
Have i allowed you to get away with this that long
As i stop and lowered my guard a little
Have I let the wrong person enter my heart again
So that I've allowed my heart to tell his-story
you fear getting hurt yet i stop letting fear control me
i let down my guard slowly i find myself
On the outside looking in hurt again
That doesn't stop me im wondering will he be better this time
maybe you'll allow your guard to drop now
that i've showed u there isn't anything to fear
but yourself you will be the cause of your unhappiness
if u don't allow yourself that feeling of joy open ur heart and prepare it to love again
