Am I overreacting?

Ok, wise people of GC -- I need advice and opinions. This is probably only the 2nd time ever I've posted anything like this.

My best friend from HS is getting married next month. Aleathia and I were as close as can be since 9th grade and remained that way well into her first few years at UNLV. Though we became "not as close" during college (as she was there and I was at UHM), we were still friends who kept in touch. I'd often travel to Las Vegas....not to gamble, not to shop...but to visit Aleathia and her BF Mike. She was my first ever friend in HS, our parents are good friends, and we're even distant relatives.

Keep in mind that I was the one who introduced Aleathia to Mike at a HS dance in 1996, counseled the both of them when they broke up for the first and second time, kicked both their asses when they tried to stray, etc. You get the point. He never confided in our other friends. Just me.

Enter Ronna and Evelyn. Ron and Ev were part of our little HS "clique". We were all friends, but Aleathia and I often thought that they thought that they were better than us.

Ron, Ev, and I all attended and graduated from UHM though we basically became strangers while in college. Aleathia would come home for the summers and breaks but I'd hang out with her separately and she'd hang out with them separately.

We get word that Mike finally proposed and wedding plans were under way. In the initial stages I helped her out as far as researching locations, dresses, etc (since she lives in Vegas) but never once did I ask who was going to be in her wedding party. I didn't mention it, and I assumed that it would consist of her little sister and her cousins (she's got a lot of em). I didn't think anything of it.

She and I were in touch back and forth and she often gave me word on what's been going on as far as planning went. And then today I get a MySpace comment on my page from Evelyn, who currently lives and works in Korea:

Hey Sandy! I'll be home in a month for Aleathia's wedding. I don't think you know, but Ronna and I are Aleathia's bridesmaids...just letting you know so there are no surprises.

WHAT....THE...FUCK?

I totally understand that it's Aleathia's wedding day and she has the right to choose her wedding party, but taking the above into consideration, I assumed that if I really meant something to her, she'd either a) consider me for bridesmaid or b) at LEAST explain to me the reasons why she chose Ronna and Evelyn and not me. I didn't think I'd have to find out from a fucking MySpace comment. What's italicized up there is Ev's exact comment, word for word. The "surprise" thing kinda struck me as odd...obviously THEY had discussed it and wondered what would happen when I showed up on wedding day to find out. I even went to her fucking bridal shower and no one said a WORD.

I know it seems like I'm overreacting and maybe I am, but it really does seem like it's a slap in the face times 100. This is what I'm thinking about doing -- I'm thinking I should just fucking boycott the wedding altogether and just send her a gift in the mail.

I really am happy for her and Mike because they've been through a lot, but I am even more angry that she couldn't even be honest with me.

Am I being selfish for not attending the wedding at all? At this point I could give a fuck about regretting later on that I didn't go to the wedding, but that's just plain DICK, ya know? Even my mom said flat out that even she didn't want to go now. I know I'm sounding like a sore bratty loser, but this hits home kinda hard.

If I don't go to the wedding on June 18th I'm thinking about taking a quick hop to the sunny So Cal to drink wine and bitch about men with Amy and Maria.

Sorry for the long post. I really should stop checking emails first thing in the morning because when you get bad news, it's so easy to just let it ruin the rest of your day.
