Spring is coming and I feel disillusioned

I am turning 39 in a few weeks time. I have been single or with utter N douchebags all my life. I am pretty much the only unmarried person at work and the very few single guys I've met and felt attracted to since my D&D were either not interested or not a good match.
It's not that I'm unhappy - I recently moved to a new city, made a nice home for myself, took up a very challenging new sport, and I have good friends here.
But we're working overtime and I have no time to meet people outside the office. To be honest I don't even try to flirt anymore, especially not with colleagues... because I know the game and it's usually Narcs who excel at it and pull me in that way.
A new cute colleague started recently but I observed him and am pretty sure he's a predator... thank God for our Narcdar!

This time last year, in the midst of my suffering, I thought:
"Well, maybe my NEXT spring will be wonderful and I will be in love with a good man." The thought kept me going...
But here I am a year later, still single, and I am starting to feel old because the big 40 is looming and this crazy Narc society has programmed it into my head that women need to be young and beautiful to be desirable. WTH! But yeah, I still need to do some serious de-programming...

I find myself thinking of Narc more often these days. He was the first man I truly loved and it's hard to forget how I felt when he smiled at me and scooped me up in his big arms.
He raised my expectations sooooo high, and I seriously thought 2011 would be one of the happiest years of my life, that we could finally be together now that his relationship was over. Then he dumped me and enjoyed spring with OW, leaving me a crying mess barely able to function.
My last birthday was a total disaster because I had the incredibly stupid idea to invite him and OW along hoping we could somehow all be friends. Of course, I couldn't handle it when he took her home at the end of the evening so I cried myself to sleep on my own birthday... :(

It's been a year now and about 5 months no contact. A friend of mine recently told me that the Narc is not as happy in his awesome new job as he had hoped to be and is possibly suffering from lack of supply. No idea if he is still with OW, but it doesn't matter anymore. I know his life is not perfect.
What still matters to me, though, are those memories of last spring... of all that pain and humiliation. Of him parading OW around in the office.. oh, did she make him look good!... while I was curled up in the bathroom crying like a baby and trying to get a grip and not lose my job.
It just makes me so ANGRY that HE will ALWAYS find a new victim, will always enjoy his spring, that Narcs and psychopaths and complete idiots manage to somehow find a partner while good people end up alone. WHY?

I don't know how to re-ignite any sort of enthusiasm for the dating game anymore. I know I should stop looking and be happy by myself, but it's hard when spring is coming and you see couples everywhere. Seriously, I wish I could just be a silly young chick and at least have lots of fun and get laid... But I was never that chick, not even in my 20s...

Any upbeat thoughts on the topic, ladies? Thanks :)
