The "Splitting" In Splitting Up

There's a lot that has to happen as you separate your life from someone else's.  Granted, we didn't own property or have joint bank accounts, but there is still plenty of stuff that needs to be taken care of/divided up/dealt with.

I planned for that.  I knew some of it wouldn't be easy.  Dogs had to be talked about, cellphones unjoined, furniture divided.  There's the uncomfortable discussion about bills that remained to be paid.  I even thought about Facebook, and how we actually weren't "linked" in a relationship on the social network.  It was a relief to not think about flooding everyone's News Feed with "Liz is no longer in a relationship."

However, I didn't plan for the disintegration of our "social" friendships.  I was unfriended on Facebook yesterday, and it was shocking and sort of hurt.  I discovered it purely by chance, a perfect mesh of timing.  

**To be honest, I didn't discover it at all, a friend did....

What's the appropriate response to that?  Obviously I can't do anything about it, but it is one of those things that I wonder about the etiquette.  Is unfriending the ex a standard?  What's the timeframe on it?  Is it ever appropriate for either party to re-friend?

I respect the idea that this might be part of his grieving process.  Part of the way he is also separating things out of his life.  And I want to make that process easy on him, or at least make it not painful.  But it doesn't mean I was prepared for this.  I am so curious about the thought process and reasoning behind it.

So many questions.  Just not so many answers.
