What not to do on a Saturday...

So yesterday, against my better judgement, I went to a bridal show with my mum. Her thinking was that attending such a show might be a lucky omen for me and bring good luck and I thought of it as a chance to look at pretty outfits and be dazzled by glittering jewels (if nothing else).
We got there and were greeted by smiling faces asking when my big day was, so I replied saying that I didn't know yet, but my mum added that I will be a bride one day. So the lady gave me a big goody bag filled with advice for brides and some Clinique goodies.

I already felt a bit uneasy but we entered the main hall and wandered around, it wasn't long before we were stopped again and asked about my upcoming nuptials. By about the fourth time I had been asked the same question, my heart had sunk deep into my stomach somewhere and I just wanted to run away. So we left.
I'm not quite sure when things changed and the 'M word' became the big elephant in the room, but something has happened. Only a year ago I remember going into Tiffany's with a friend and having such fun trying on engagement rings that an imaginary man would buy for me.
But now, in 2012, I feel like a cross between Carrie Bradshaw, Bridget Jones and Muriel Heslop. Suddenly, I feel awkward about being single, with no marriage or engagement in sight. I don't want any well meaning individual to remind me of this plain fact. Being in a room full of excited future brides only reminded me of my own inadequacies and left me feeling really small.
After 6 years of dating, what can an eternally single girl do to keep the magic alive?
