PSM, I really get where you're coming from. I have moments of thinking the same myself, but am leaning more towards MaggieBeBold's approach: I'm working towards being content and independent on my own, and if/when I meet someone down the line, they'll be a bonus - not the be all and end all; if it doesn't work out, my life will carry on fairly unscathed.
Sometimes this makes me feel sad, especially as I'm only 31 and most of my friends are settled with seemingly lovely men and just starting their families. It's a problem borne of circumstances more than age. I have one single friend left, who lives over an hour away. When I'm free for a night out, most close-by friends are having couple/family time.
So taking my eye off the relationship ball, and refocusing it on me and my aspirations, and DS, is helping. There are some things I want to do, to accomplish, and throwing some energy at these is a great distraction - and maybe they'll lead to something in time?
There's a quote about how happiness is like a butterfly: if you chase it, it flutters away; if you sit quietly and turn your mind to other things, it comes and perches on your shoulder. I'm wondering if love can be the same. This could be bollocks, of course, because most of us are stuck in of an evening and the odds of meeting someone are stacked against us in these circumstances! But I do wonder if not pursuing love and instead focusing on other interests and activities, will somehow lead us there when we're least expecting it. And how many people find a decent relationship as a result of actively looking for one?
Ramble over! I do understand where you're coming from.
