This week I am going to see a school friend of mine get married. She is only the second of my peers to tie the knot - the first, Louise, was aged only 21 and has now given birth to two children.

Since she was so young when she exchanged rings, she is considered to be rather out of the ordinary, so her wedded state has not worried me - until recently.

Now that my school friends have all turned 27, my married friend is no longer the anomaly, but a trend setter, the first in a long line of my mates who are lining up to walk down the aisle.

And next year, another school friend, Clara, is tying the knot, as well as a university friend, Poppy, who is nearly three years younger than I.

Some of you might imagine that this has put the wind up me a little. My single friends are dropping off the twig like overripe pears, plummeting to earth to shatter in a shower of juice and seeds.

But I have refused to let it get me down. After all, all these friends are female, and everyone knows that women are more likely to get married earlier than men.

So I have taken heart at the single state of my male friends. Several of them don't even have girlfriends, and the ones that do certainly aren't planning on marriage any time soon.

However, I got the news last week that my latest ex-boyfriend, with whom I broke up with nearly three years ago - is now engaged.

He is a year and a half younger than me, so it did make me stop and think.

His betrothal means that out of the three serious boyfriends I have had, all three are engaged. The two others, including my childhood sweetheart, have even gone so far as to buy houses with their fiancées - a move universally acknowledged to be as much of a financial and legal commitment as getting married.

All this has made me take a step back and look at my single friends. How many do I have left?

Of course there's Kat, my reliably single housemate. I have one school friend who remains single - although she yo-yos between boyfriends and singledom every few months.

And one of my best buddies from uni, Dave, remains a bachelor.
That's it

Should I be worried? I am happy with my life, of course...but as these weddings increase, will I start to feel more like a Bridget Jones character?

I have decided that I am the only one in control of how I feel. And I have decided NOT to feel like that - and to carry on enjoying being single for as long as it lasts (even if it is for the rest of my life).
