It was me

I have never loved like this before
When you left me my heart hit the floor
I understand what I did wrong
I was jealous and hurtful for so long
I can only say sorry and hope you’ll see
That that person wasn’t really me
I was so scared of losing you I built up this wall
I thought it would help me
But apart we did fall
You came back to me
But not long enough to see
Please let me show you the real me.
