personality clash

I have been struggling with getting along with people this week. Not people in general ,but certain people. One of my friends in particular is DRIVING me CRAZY!!! I can't stand being in the same room as him. I can't handle ANYTHING that he has to stay, everything that he does is making me angry.

I have been trying to wrap my head around it all week. What is making me so angry? ... There's a good chance that I am going to get called out on it soon. Almost every minute of my life is near or with this guy. I don't think he is "doing" anything wrong, but he had a change of mindset which is making him act and behave differently. I think things in the past few weeks have made his head big and need to let everyone know that he is "it"

Part of me feels like I can't be mad at him. I often start to feel like I'm "it" and people are still nice to me, even when I am all full of myself.

But, I just can't do it in this situation. I am sick of getting his two-cents on how to do my job, I am sick of hearing his two-cents on how my co-worker should do her job. I am sick of him trying to get close while "up-one'ing" to the camp staff that came and did their own retreat at our camp this week. I am sick of all the acting and over confidence spilling out of him, the hurtful words that come-out of his mouth to make him sound better. I am sick of the whole entire prideful veneer that he is putting on.

So, now that I know how I feel, what do I do with it? Wait for it to go-away? Call him out of it? Avoid him? I really don't know.

There has been 3-5 other seasons of this attitude that I have experience with him in the past, but it has never lasted this long. I have always qualified it as a bad day, but maybe there's more going on than that. But, I don't how to deal with the issue that causes this personality that I cannot handle to be around. Maybe I need to focus in on what is causing this behavior to come out, and try to work with him in addressing the issues that are causing this terribly annoying personality to come out of him.

or maybe I will just continue to avoid him until her demeanor changes.
