Forgivness...?

Three months...
Almost four months have gone by...
We haven't talked nor seen each other much over those months...
A lot has happened during these last for months.

New life,
New "love,"
New everything.
I should be happy...
But all I feel is regret...longing...and most of all...
Used.

The one feeling I hate anyone feeling.
Yet now I have this feeling.
Not from moving on, but from the one whom i moved on from...
I should not feel this,
But it haunts me every day and night.

Why can't it all be forgiven?
Why can't it all just disappear?
Why must it haunt me every waking moment...
Every nightmare?

How can I stop it?
How can I show that I AM sorry?
To show that I still care?
Still want everything to be close to what it used to be?

How can I show my sorrow?
When will you realize that I regret it?
Regret giving up the one I wanted the most?

How can we both get and receive forgiveness for what was done and said?
