How funny, that an anti-dating thread has become a flirting thread. 
Seriously, I’m another one of those people who wasn’t looking at all when I met the love of my life. And, interestingly enough, she had also recently stopped looking after a particularly rough breakup. I never imagined someone I was never looking for could make me so happy.
That said, I try to make it a point not to say that others will find the same happiness. If someone, like Eve, seems happy and content being single, then more power to them. The reasons don’t really matter. If they’re truly happy, then that’s all that really matters.
It should be said, however, that there are those who try very hard to convince others, and so convince themselves, that they are happy being single when they really aren’t. Case in point: one friend of mine I knew in college, who told me time after time that she would happily be a crazy old lady living alone with her dogs, never attached to a man at all. Now, five years later, she’s living in New York, with a guy she met a year ago or so, and she’s frankly never been happier. She does still have the dogs, but in her case I always knew that her “I’m happy being single” line was nothing more than a smokescreen, a defense mechanism against her real feelings.
Some friends, being able to perceive this sort of fakery in people they know and love, will not hesitate to point it out. I was not one of those… I never said much of anything, but I always knew that she would only really be happy once she found someone to be happy with.
However, I only point that out to clarify why reactions to the “I’m happy being single” line are mixed. Sometimes it’s true, sometimes it isn’t. I have no reason to feel that it’s anything but genuine for Eve, though, and I wouldn’t presume to say otherwise.
I hope you find true happiness, Eve, in whatever form it comes to you.
