What do you do with distance?

Based on current happenings….

I have this…friend.

(To save me the stress of beating around the bush, this friend is a male. To save you the stress of looking for hints, there is no sexual drama involved here.)

Now that that’s established, let us move on.

I have known this person for about 7 going on 8 months. We worked together for that duration and we got close... We would talk (read chat) and joke well into the night, see the next day and joke and play till we closed.

Imagine how I felt when I started sensing attitudinal shifts and changes. There were some work issues that probably caused this but I was of the opinion that my not wanting to discuss SOME work things should really not affect our relationship.
(It’s the general school of thought that that’s wrong but put a let's bookmark in that)

The little shifts gradually grew to become a dark spot we both didn’t address. He attempted to discuss it (I just realized that in retrospect) but he said some things that were, in my opinion constructed to scare me and so I kept a resting bitch face during the entire discussion. I kept mute. At the point where I decided to talk, he closed up.

I was frustrated and frankly, uber pissed.

We spoke (read chatted) again briefly and I thought all was well. But it wasn’t.

Now we have a big chasm (and I’m in a don’t know-slash-not-sure-how-slash-don’t-know-if-I-want-to-be-the-one-to-fix-it kinda state.)

But back to the point, what do I do with this distance? I hate it. 

UPDATE:  A week later. I'm over it. He's trying to be friends again. -_-

UPDATE of UPDATE: I needed his help. -_-

The End.

P.S: This post went a different way than the actual plan.

The question: What do you do when distance develops with someone you were once close to?
