She wts to arrange my flowers and buy them for all of the bridal party, mothers, and my bouquet- how nice

.... BUTTTT I really had my heart set on anemones and she wasnt expecting I would want anything other than a rose and seemed taken back by the amount of BM (7 girls) and the price. I really dislike roses so I told her what I wanted and said if that was over what she intended to spend I would be happy to buy the flowers and she still arrange them --- now I think I offended her... It feels like a rock and a hard place
