Would you get funny? Jealousy issue?

Meeee, again lol
Sorry to keep on today but on tis one any advice would really help.
Let me explain the situation....i met h2b 2 months after my best mate got with her guy - when i moved away - they split up but got back together about a year later.
Now as some of you know she was meant to be BM at my December wedding....around the time i booked my wedding her and her bloke were on rough ground, spes as he was away with the army in Afghan....when he came back 2 about a month ago they made up and he proposed...she accepted and they were looking to set a date for September 2011 time....in the meantime as said before a few days ago i postponed untill the 21st of July - i text her to tell her and her first reply was 'why?' i went onto explain to her and she text then to say they had booked a venue for the 5th of August!
Now iam really happy for her and personally think its amazing that we are nearer enough date twins - but it dosent look like she shares the same opinion...i then went onto to text her 'we can plan together now' ( in an non patronising non pushy way) i never heard from her again that day.
Now im used to my oldest friend texting me every other day - she has not done this since my text about the change of date. I text her earlier to see if she would posibly want to enquire about a joint hen do - her reply, short and sharp - 'not having it abroad sorry' that was it!
Now some of you might be thinking...iam being abit over the top and over reacting, but i know her better than most and she is not usually this cold or offish - do you think it could be that she feels peed off that my wedding is just before hers? Maybe she feels abit 'put out' that i will get the attention from our friends before her? Ahh i dont know! She just seem to have gone weired all of a sudden. i personally couldnt care if mine was the day after hers....aslong as we both had the most amazing day! How would you feel girls if you were her?
I dont want her to feel like that but i also know she can be the jelous type from time to time.
I have not been pushy atall, just an excited friend happy for her, ive offered her that if she wants any help or advice planning her wedding im tere for her - but its like shes starting to blank me.
Any advice or opnions here.....?

Maybe you are right, she is annoyed that you have 'stolen her thunder'. But the thing is, there is only so many weeks in a year, when would she have you get married? Anytime as long as its after her? Its not a competition, its not a race, you picked another date that was suitable for you, she shouldnt really be acting funny with you!

Dont get me wrong, I think its natural for her to be a bit annoyed. Well maybe annoyed isnt the right word. I dont know what the right word is. I hope she is just having a wee moment to herself, and you two can get on with being friends and helping each other out with the wedding plans.
