Druidh put it best for me when he said:
“I don’t believe that there is only one person in the whole world for each of us. Chances are that you’ll meet several potential partners, before, during and after any ongoing relationship.”
He’s right. I share your pain; there’s a girl I treated in a very similar way, and now I’m sort-of friends with.
Its hard. Sometimes I look at her and think: hmm.
But then: my wife is lovely, and my kids are lovely, and that’s always worth fighting for.
I know now, years later, that it could have worked with her, but you know what? It didn’t. And there’s a family who needs me very much. And maybe in a few years time, I’ll meet someone new who’ll stir me up too.
But hopefully now that I’m older, maybe wiser, I’ll use that experience to identify where I’m falling down in my own life, and work on the gaps.
Be strong, and realise this (and this may not be a comfort):
you don’t need to move on, because time has passed and, sadly or not, you’ve both inevitably already done so 🙂
