The worst part about walking away from you, is knowing you're not going to stop me. - Unknown

I guess to some extent you get used to being alone.  You get used to not expecting phone calls and having nothing to do at night.  You don't expect to turn around to open arms any longer.  The small sounds of her have been replaced by silence.  Your thoughts echo through your head, with no one to share them with.  All in all, being alone isn't terrible, it just hurts.
