huge dilama...kind long

ok i really need some advice because i am very undecided about something....
my best friend has been planning to get married for a very long time. about 4 other times she has made plans and arrangements to get the wedding plans on a roll. booked her hall, photographer,ect. then after 3 months decides that she is not ready. well she just notified me and my fh (we both are in the bridal party) that she will be getting married oct 1, 2005. a small intamite wedding. thats fine and i am very happy for her and she says that she is not going to change her mind anymore(which she has said everyother time she has announced her wedding). the only thing that i am worried about is i live in florida now and i cant go and book plane tickets and have her decided that she is not going to get married. what i am supposed to do????should i take the chance or not????? tickets, plus buying my bm dress, and a gift is a very expensive. help girls??????????????????????????

some airlines offer refunds...so i would look into that . as for the dresses, wait for the last minute to order them... i have a friend who got stuck with an ugly bridesmaid dress that she never got to wear! other than that, i can't think of any other advice to give you...
