Being ignored by a "friend" (venting)

Eh, just have to write this out as I've been keeping it together for a while now and I'm just fed up with it.

Me and this guy from work used to be pretty good friends, at least we talked and joked around and were on generally good terms. Suddenly 3 or 4 months ago he started ignoring me and this other girl at work, which he's recently become friendly with again making me the only one being ignored. At first we both figured he was just in one of his moods, that he gets bored with people and flutters from person to person. He's done this silent treatment to me before twice and I already deemed him not a friend, but I figured having a pleasant work relationship was okay and makes work more bearable. (I suppose the opposite is true too! Obviously ha ha)

I'm getting so fed up with the treatment, he comes in to work says nothing, no acknowledgment(hi, sup), will talk to whomever else is present, but treats me like I'm not even there. The worst part is we're co-heads of projections and need to EXCHANGE information, but he WILL NOT talk to me. It's so frustrating because all I ask is to know what's going on and you can go back to ignoring me all you want you son of a bitch! Like one Monday I was going to start building a print because I assumed it needed to be done, I got one reel in and he comes over saying "You don't need to build that... -some other stuff- ...My bad, my bad..." All mono-toned and like, I wasn't going to say anything cuz I don't care, but since I saw you doing it. And all of our exchanges are like that now, him telling me something the last second or not telling me at all and I find out from someone else(coworker/manager/fuck a stranger off the street is probably better informed then me). Of course it makes me feel like I end up looking bad.

I feel like it's worst now that I accepted the management position. Now he probably feels like I'm a traitor or something. I always told him that I didn't want to be manager, but you know one of the reasons I decided to do it was because he was doing this shit and I want out. Not many jobs looking for a projectionist, but plenty can use a manager.

Really I'm started to hate his guts, because he plays these stupid games. AND HELL NO don't try to ask him why he's not talking to you or if he's mad at you, because then you don't "get" him and aren't (apparently) his friend. I made that mistake during the first ignore/silent treatment.

It makes me hate working with him, especially now that I'm the only one being ignored, cuz now there's like fun/happiness going on around me, but I'm not really included or I'm an interloper.

It's been really weird lately, like I don't fit in with projections anymore because I'm a manager and I don't fit in with the managers because I'm new. Makes a person feel really lonely.

To end this on a positive note, there are really nice people around me that are friendly and fun, but I'm not around them much and I wouldn't want to cling to them. Not to mention I've had this feeling lately that people get bored of me quickly or they just aren't really that interested in me... (oh no the positive note is slipping to a flat!)

Sigh... was nice to complain, but I don't know it doesn't make me feel much better... I guess because I know I'll still have to deal with it during the week.

I know it sounds like I'm depressed, and actually some days I am, but I'm mostly frustrated and ready to move on in my life. I guess, even though I know I can't right this second, that I'm taking steps toward doing that.
