I responded this morning

He sent 2 emails yesterday.....I couldn't let him think something happened to me.
 
I just reponded "no, business trip is next month.  I'm okay.  How are you?"  He wrote back saying "I'm good.  miss ya."  That was almost at 2am. 
 
I'm sure he wants me to ask about tonite.  I'm not asking.  I'm sure he knows I'm trying to pull away.  He knows me.  It's been 13 years.
 
I don't think I can be in contact with him when we're done.  I think it will be too hard.  I understand the need for NC.
