How to not hurting you again?

My heart is weeping tears of blood for the pain that I've caused you,
And it's crying out my apologies to your mind,
Pleading for your forgiveness for my unfortunate outbursts,
I never meant, in a million years, to be so unkind.

I have made mistakes in the past but never as serious as this,
And I know I will only have myself to blame if you leave,
And that scares me more than I've ever been scared in my life,
For you're my true motivation, the only real thing in which I believe.

Everything else is just a fantasy to my egotistical ideals,
It's always been me, me, me for far too long,
And lately I haven't given even a passing thought to your concerns,
I let them all fly past me, but now I know I was wrong.

You were reaching out to me in your time of uncertainty and sorrow,
While all I cared about was me and what was mine,
And as I watch you pack your bags with tears streaming down my cheeks,
Too late, I feel all your angst and pain.

And all that's left for me to do is say sorry in a sincere way,
With an apology that comes from deep inside my soul,
It's all I have left to offer for your love and your loyalty,
It's just a pity that my own loyalty, I couldn't hold.

Now all I have left of you are the memories of the goodness I have lost,
And that loss brings a sadness every time I think of your name,
And my heart yearns to be able to turn back the hands of time,
To correct the mistakes I've made and start again.

So please take time to think about what I've said, as it comes from the heart,
Take time and try to forgive me my failure to deliver,
And if you can't, then cast me out of your life never to return,
And I will hang my head in shame....... forever.

Maybe i should let you happy without me
