I think I can understand - there was a girl I was involved with for a while, although we finally stopped a while ago. I said goodbye to her fairly recently, just to really close the book. And in all honesty, she was incredible - not just beauty-wise, but incredibly smart, funny, caring, etc. For specific reasons, it wouldn't have worked out as a shidduch, but if I thought it would have had a chance, I'd probably be married now.
And I miss...yeah, I guess the way being with her made me feel. She had an ability to make me feel special, wanted, understood.
But I still know that moving on was a good move (a move she supported me in, knowing how good it was for me), and that helps me walk taller, feel a weight lifted off my shoulder, and move forward, even if I still miss her a bit.
