September or December wedding??! Friend upset if I wed before her!

Hi everyone! I just want some outside opinions/advice as to whether I should keep my December date or change it to September.

My friend has had a 4 year engagement - finally getting married October 2014. My FH and I got engaged labor day weekend and have been together for 7 years. The day she saw the ring she said it would be a great idea to get married labor day weekend the following year and I said before you?! No way.

We decided we should get married after them because it seemed like the right thing to do considering how long they waited.. but didn't want to wait 2 years to get married since we have been together a long time - so booked a venue for early December 2014.. I have since been hesitant about the weather but keep pushing it out of my mind.

Now my friend wants to make sure her bridal shower and bachelorette party are 'first'.. which is making me really stressed/upset that she never appreciated me booking my wedding after hers and cares so much about being 'first' for this silly junk that doesn't matter. I just want to get married and she is complaining to my other friend who is her maid of honor.

NOW IN THE MEAN TIME - I get offered a permanent position at my job and they are not happy about me leaving for a 2 week honeymoon in December because it is our busiest season. So because I am so annoyed about everything I call the venue and see if they have any other days Sept/Oct/Nov - the only date they have is Sept 1st.. labor day and the same price! Which would be so meaningful since it was the weekend we got engaged. I am afraid to even speak to my friend about this idea - but is she even a good friend anymore if she is so selfish?? I know all of this won't mean anything in a year but I am so indecisive about a December wedding as it is and want my honeymoon to at least be everything I ever dreamed of!


Please share any thoughts you have!!! :)
