So sorry to hear you feel this way don't. Long term lurker here but felt I needed to post.
As someone who is much happier without the hassle of relationships, I've learned that a busy life and great supportive friends can truly be the best thing ever. If internet dating isn't working for you, then give it a good break. You need a thick skin and a hefty dose of 'Oh well, his loss' to do it!
I second the idea of forcing yourself to leave it well alone til 2015 and focussing on YOU instead. What do you like? What have you always fancied trying? What's on locally that you would have always liked to try but didn't as you were spending the time dating/with a man? There are only so many hours in the day and thinking about dating takes up headspace which could be freed up for other, more enjoyable things! (Make no mistake I love men but I CAN do sex with no strings so I enjoy that and then get on with the rest of my life)
My sister has travelled all over the place and went to Oz on her own to live ten years ago. She built up a great network by, as she says 'whipping my diary out whenever someone suggested getting a coffee and putting a date in'. Friends introduce you to friends and so it grows. With time and effort you have a great circle and a good life that you're actually thinking 'This guy had better be AMAZING for me to give up any of this for him'!
It's partly the way our society looks at relationships. Every engagement (no matter how unsuitable) is wildly congratulated, we're asked if we're 'still single' and lo and behold you can feel less than without a man. Friendships can be just as good, if not better and on your own doesn't have to be lonely if you take the time to do lovely things with and for yourself. REFUSE to buy into the crap about not cooking for yourself or it being 'weird' to do stuff alone. Learn what you want and like and take some time to do it.
There are no roadmaps for being single really. I once lived with an idiot who said it was 'the bit in between boyfriends' but it can be the best bit, when you find out who you are.
Whether or not you meet someone in 2015 or 2018 or whatever, take this time as precious time out. And invest in a shit hot vibrator for the other stuff.
HTH
